Topic: anonimous russian masters

hi, all! I need help to remake my collection of works of an unknow russian master (circa '70s), example: pic "1". I have the complete collection long time ago, but I lose it. Anybody could post?
and I need too some information about the pic "2". Anybody knows who is the artist? I think he's russian too, but I'm not sure. Well, that's all. (Please, excuse for my very bad english)
