I've gone back to the same dealer in Russia three times now to purchase paintings by Chaloi Leonty, whose estate the dealer handles; I just think he was a really good landscape painter, and Russian prices are pretty good! This impressionistic oil on cardboard may be my favorite yet--really a little gem of a painting, and I could look at that sunlit tree against painterly clouds and radiant blue sky all day. I might guess this was was painted along the coast on the Black Sea, but I don't know for sure. 

Signed on the back, and dated 1965. From what I understand, Leonty was born in 1929 in the Urals, and graduated from the Leningrad Art College in 1955, where he studied under G.A. Shah, a student of Ilya Repin. He then worked at the Combine of Fine Arts in the 50s and 60s--a production subdivision of the Leningrad branch the Art Fund of the RSFSR--and in 1975 joined the Soviet Union of Artists. At least from what I have seen, landscapes seem to have been by far his most frequent subject. 

Very good condition, with minor wear along the bottom corner edges, very minor.   5" x 7".
