A beautiful view of The Topkapı Palace in Istanbul (Turkey).

Wiki says:
The Topkapı Palace is a palace in Istanbul, Turkey, which was the official and primary residence in the city of the Ottoman Sultans for approximately 400 years (1465-1856) of their 624-year reign.
The palace was a setting for state occasions and royal entertainments and is a major tourist attraction today, containing the most holy relics of the Muslim world such as the Prophet Muhammed's cloak and sword.
Initial construction began in 1459, ordered by Sultan Mehmed II, the conqueror of Byzantine Constantinople. The palace is a complex made up of four main courtyards and many smaller buildings. At the height of its existence as a royal residence, the palace was home to as many as 4,000 people, formerly covering a larger area with a long shoreline. The complex has been expanded over the centuries, with many renovations such as after the 1509 earthquake and 1665 fire. It held mosques, a hospital, bakeries, and a mint. The name directly translates as "Cannon gate Palace", from the palace being named after a nearby gate, which has since been destroyed.
Topkapı Palace gradually lost its importance at the end of the 17th century, as the Sultans preferred to spend more time in their new palaces along the Bosporus. In 1856, Sultan Abdül Mecid I decided to move the court to the newly built Dolmabahçe Palace, the first European-style palace in the city. Some functions, such as the imperial treasury, the library, mosque and mint, were retained though.
After the end of the Ottoman Empire in 1921, Topkapı Palace was transformed by government decree on April 3, 1924 into a museum of the imperial era. The palace complex is full of examples of Ottoman architecture and also contains large collections of porcelain, robes, weapons, shields, armor, Ottoman miniatures, Islamic calligraphic manuscripts and murals, as well as a display of Ottoman treasure and jewelry.

The postcard from Supattra depicts the Ubon Ratchathani Candle Festival in Thailand.

Wiki says:
The Ubon Ratchathani Candle Festival, the most elaborate of the traditional parading of candles to wats, is held in Ubon Ratchathani, Isan, Thailand, around the days of Asanha Puja (which commemorates the Buddha’s first sermon) and Wan Kao Pansa (which marks the beginning of vassa).
At the start of the Lenten period, it is traditional in preparation for the rainy season for the devout to donate to items for the personal use of monks, and of candles to dispel gloom in their quarters and elsewhere within the wat. The latter is often the core event of many village celebrations, but is at its most elaborate in the Ubon Ratchathani version, which nowadays is a major event both for residents and for tourists: giant candles are paraded through the town, each representing a local temple, district or other institution. The more elaborate versions are accompanied by scenes of Hindu and Buddhist mythology sculpted in wood or plaster and coated with wax. Of course, these candles are never burned.
The candles are carved a couple of days before the procession.
On Asanha Bucha day, the candles are taken to Thung Si Mueang, a park in the middle of the city, where they are decorated and then exhibited in the evening. On the same evening, there are small processions with lighted candles at several temples.
The procession takes place on the morning of Wan Kao Pansa. The candles are paraded through the city centre on floats, accompanied by representatives of the respective institutions. These are normally dancers or musicians in traditional dress.
In addition to the above, the festival is accompanied by the usual paraphernalia of feasting and games which attend any Thai festival.

Today I found in my mailbox a real treasure. Felice from Chicago (USA) sent me an amazing postcard of Frida Kahlo and an envelope with two cards of Diego Rivera murals!

Christoph from Dortmund (Germany) sent me this beautiful postcard with a fragment of Sandro Botticelli's "Primavera" ("The Spring").  

Wiki says:
"Primavera", also known as "Allegory of Spring", is a tempera panel painting by Italian Renaissance artist Sandro Botticelli (c.1445-1510).
Various interpretations of the figures have been set forth, but it is generally agreed that at least at one level the painting is, as characterized by Cunningham and Reich, "an elaborate mythological allegory of the burgeoning fertility of the world". Elena Capretti in "Botticelli" (2002) suggests that the typical interpretation is thus:
The reading of the picture is from right to left: Zephyrus, the biting wind of March, kidnaps and possesses the nymph Chloris, whom he later marries and transforms into a deity; she becomes the goddess of Spring, eternal bearer of life, and is scattering roses on the ground.
Venus presides over the garden, the Graces accompanying her, while Mercury's caduceus keeps the garden safe from threatening clouds. The basic identifications of characters is widely embraced, but other names are sometimes used for the females on the right. According to "Botticelli" (1901), the woman in the flowered dress is Primavera (a personification of Spring) whose companion is Flora. Flowers spring from Flora's mouth at the contact with the wind god.
The pastoral scenery is elaborate. "Botticelli" (2002) indicates there are 500 identified plant species depicted in the painting, with about 190 different flowers.
The history of the painting is not certainly known, though it seems to have been commissioned by one of the Medici family. It contains elements of Ovid and Lucretius and may have been inspired by a poem by Poliziano. Since 1919 the painting has been part of the collection of the Uffizi Gallery in Florence, Italy.

"The Baleful Head", c.1876 by Sir Edward Burne-Jones. This postcard came from Monique. She is from Bowling Green (Kentucky, USA), loves candy, indie-folk & "The Hitchhiker's Guide to the Galaxy".

Wiki says:
Sir Edward Coley Burne-Jones, 1st Baronet (28 August 1833 – 17 June 1898) was a British artist and designer closely associated with the later phase of the Pre-Raphaelite movement, who worked closely with William Morris on a wide range of decorative arts as a founding partner in Morris, Marshall, Faulkner, and Company. Burne-Jones was closely involved in the rejuvenation of the tradition of stained glass art in England; his stained glass works include the windows of St. Philip's Cathedral, Birmingham, St Martin's Church in Brampton, Cumbria, the church designed by Philip Webb, All Saints, Jesus Lane, Cambridge and in Christ Church, Oxford.
Burne-Jones's early paintings show the heavy inspiration of Dante Gabriel Rossetti, but by the 1860s Burne-Jones was discovering his own artistic "voice". In 1877, he was persuaded to show eight oil paintings at the Grosvenor Gallery (a new rival to the Royal Academy). These included The Beguiling of Merlin. The timing was right, and he was taken up as a herald and star of the new Aesthetic Movement.
In addition to painting and stained glass, Burne-Jones worked in a variety of crafts; including designing ceramic tiles, jewellery, tapestries, mosaics and book illustration, most famously designing woodcuts for the Kelmscott Press's Chaucer in 1896.

The cathedral of Epiphany in Yelokhovo (Moskow, Russia). Sent by Assja.

Wiki says:
The Epiphany Cathedral at Yelokhovo, Moscow, is the vicarial church of the Moscow Patriarchs. The surviving building was designed and built by Yevgraph Tyurin in 1837–1845.
The original church in the village of Yelokhovo near Moscow was built in 1722-31 for Tsarevna Praskovia Ivanovna. It was there that Alexander Pushkin was baptised in 1799. In 1790 a refectory with a four-tier belfry was built.
The present structure was erected in 1837-1845 to a Neoclassical design by Yevgraph Tyurin. The architecture is typical for the late Empire style, with some elements of European eclectics. The riotous opulence of the interior decoration is due to a restoration undertaken in 1912.
The main altar is devoted to Holy Epiphany, the Baptism of our Lord and Saviour Jesus Christ. The cathedral has two side-chapels: the left one of St. Nicolas, Archbishop of Myra in Lycia, the Miracle Worker, and the right one of the Annunciation of the Blessed Virgin.
Most venerated shrines of the cathedral are the relics of St. Aleksiy of Moscow, and the miraculous Kazan Icon of the Mother of God.
