[Amateur]

Proposed here is a sketch. Oil on board, 22h32, see Captions not. On the back of the stamp but thin cardboard factory. Commons is a stamp in violet ink (as yet 30 years ago put on a movie ticket) 24 Apr 1956 "(possibly 1953). Preservation of paintings and cardboard such age appropriate. On the flip side also has an inscription in red pencil, "Marton A.", made by someone unknown. Most likely, not by Marton, he has another signature.

I watched the work of AA Marton in the network, like, really like him. What is the opinion of experts Carpathian painting?
