A friend asked me if I wanted to buy some old paintings she had in her attic (Of course I did!) - So I went up & after crawling through dust dirt & foam insulation I found these 2 paintings? Prints? on metal plaques in great old frames. What are these? Did Picasso prints or paintings come on metal - because I can't find any? I bought them as much for the frames as the art (which I'm guessing is print but there is 1 spot that looks like a drop of paint rolled for a little bit!) - are the frames valuable - they are both by Revel? Also, how do I clean them? They have ... dirt & fur? fuzz? (something I can scrap off with my finger) - can I hose them down since art is metal (and the metal looks like it's starting to rust on the back) ? They looked stained at the bottom - I can paint them if needed, right? As always I appreciate any help.
