but I think that this is not litograviya

No self-respecting artist would not write on the plywood (if we're talking about old paintings), the more so as plywood, you have shown - machine tools, rolling, and as you know it did with the 30-ies of the 20 th century. Frame and other attributes - Modern (t.e.20 th century). "Zelenuha" in the press and lack of proper craquelure-too argument! The absence of any smear or symptoms of paintings in the best case - an attempt to recreate the lost work.
