The things that I noticed, were, the thing that looks like an old paint can, it's shadow goes back toward the wall, and the shadow of the small glass jar goes to the right, not toward the wall,...
about a foot below the hammer head(?), on the wall is the word "tea" upside down, but a lot more faded than the word "schilling",...
the word schilling looks "enhanced" and the font looks out of place,... the whole shelf scene looks too clean for the amount of decay, and time elapsed for that amount of decay to have taken place.
My 2 cents.
