I do not think it is worth alot…even if it is rare as I found much information doing searches with : Meisterwerke der Malerei. Alte Meister. Zweite Sammlung.
I wanted to break up the set and get the rembrant and a few other of the famous works matted and framed for the wall and was concerned I would damage a set that is worth alot…but I think I have found it for sale at a rare book store online for $ 150.00 US…but again I could be wrong…
Anyway…I want them on the wall in my office…I like old charcoal lithographs…so screw it…I am breakin it up.
