Cardboard Oil 57 * 37 seems to read Pop Sandor

In Hungary, taken in the signatures to put the name first, and then the name. But, alas, among the more or less well-known Hungarian (and other) artists who had the name of Sándor (Sándor), there is no matter who had the signature as on your picture. There Sandor Papp (Papp Sándor, 1868-1937), even has themes similar to yours, but it - not him. Skill level above him, and signed it "Papp S". It seems to me that the name of your artist consists of 4 letters. If you give a better quality photo captions, you can try to search further.

This is our artist had only recently moved to Hungary picture painted in 1972
