On April 1, 2019, Vietnam Post issued the "Vietnamese Silk Painting" series, consisting of four stamps.

Silk painting is a traditional art form in Vietnam with a centuries-old history. However, for quite some time, Vietnamese artists borrowed themes and techniques from Chinese masters.

Vietnamese silk painting truly flourished in the 1930s, when Vietnamese artists became acquainted with classical European painting. This period saw a rethinking of the traditional art of silk painting. Vietnamese artists managed to preserve national traditions and breathe new life into this art form: outstanding artists working in the silk painting genre emerged, and original silk painting techniques were developed. Modern Vietnamese silk painting is characterized by the use of a color palette with natural tones and a unique paint application technique, which lends the paintings a lightness and poetic quality.

Vietnamese artists who graduated from the Indochina Higher School of Fine Arts created numerous unique works on silk, which have become the pride of Vietnamese fine art. Today, silk paintings from Vietnam are held in many private collections and exhibited in museums around the world.

The stamps in this series feature works by contemporary Vietnamese artists working in the silk painting genre: Nguyen Thu, Nguyen Trong Kiem, Vu Giang Huong, and Le Thi Kim Bach. The first stamp depicts "Uncle Ho on a Working Trip" by the renowned artist Nguyen Thu.

Artist Nguyen Thu was one of the first students at the Vietnam College of Fine Arts (now the Vietnam University of Fine Arts), studying from 1957 to 1962. After graduating, he became a lecturer at the school, later serving as director from 1985 to 1991.

Nguyen Thu immediately developed a passion for silk painting and remained faithful to this genre throughout his artistic career, achieving unprecedented mastery. As the artist himself said, he found a lightness and romanticism in silk paintings that resonated with him. The soft, delicate, and translucent texture of silk demands meticulousness and even refinement from the artist in the process. Nguyen Thu's silk paintings are distinguished not only by their poetic beauty but also by the unity and dynamism of their artistic images. The artist's paintings convey the artist's emotions, his admiration for the beauty of nature, and the harmony between nature and people. The people and landscapes of Vietnam's mountains are the subject of many of Nguyen Thu's works.
In his work, he captures the clarity of the mountain air and the vastness and space of his native country. Nature and humanity are the main protagonists in his paintings.

Nguyen Thu has made a significant contribution to the development of modern silk-screen printing techniques. In 2018, a major solo exhibition of Nguyen Thu's works was organized to commemorate his 88th birthday. Nguyen Thu is one of the few artists who have dedicated their life to silk painting, and he has created over 300 works. Despite his advanced age, Nguyen Thu continues to create. He says that an artist who stops picking up a brush every day ceases to be an artist.
