Very nice stamps. Paintings by famous Russian Painters Petrov-Vodkin and Kustodiev.

Kuzma Sergeevich Petrov-Vodkin, (November 5, 1878 – February 15, 1939) was an important Russian and Soviet painter and writer. Until the mid-1960s, Petrov-Vodkin was nearly forgotten in the Soviet Union after his curtailment of painting and turn towards writing. Petrov-Vodkin writings were republished in the 1970s to a great acclaim, after a long period of neglect. His most famous literary works are the 3 self-illustrated autobiographical novellas: "Khlynovsk", "Euclidean Space" and "Samarcandia". The second of these is of particular importance, as it transmits Petrov-Vodkin worldview as an artist in great detail. Petrov-Vodkin also gave professional support to Rachel Kogan, who was his protégé and friend. The largest collection of Petrov-Vodkin's works is in the Russian Museum in St Petersburg, where, as of 2012, a whole room in the permanent exhibition is devoted to the painter. A memorial museum was also set up to Petrov-Vodkin in the house he built for his parents in his home town of Khvalynsk. It displays a selection of his works, as well as works by other Khvalynsk painters.

Boris Mikhaylovich Kustodiev (7 March [O.S. 23 February] 1878 – 28 May 1927) was a Russian painter and stage designer. In the first years after the Russian Revolution of 1917 the artist worked with great inspiration in various fields. Contemporary themes became the basis for his work, being embodied in drawings for calendars and book covers, and in illustrations and sketches of street decorations, as well as some portraits (Portrait of Countess Grabowska). His covers for the journals The Red Cornfield and Red Panorama attracted attention because of their vividness and the sharpness of their subject matter. Kustodiev also worked in lithography, illustrating works by Nekrasov. His illustrations for Leskov's stories The Darner and Lady Macbeth of the Mtsensk District were landmarks in the history of Russian book designing, so well did they correspond to the literary images.
