Having read this carefully ( and other) forums , I understand that probably this picture except that the hole in the wall-paper cover . But still - what if any value is still , and if so, what about ?

 Picture of the trophy , 1945. , Written on the plywood ( on the back of a German agitation ) , the frame is not tsenosti , size 120 by 80

 In the picture - the overall plan and without a flash , a couple of details , the signature , the reverse side
