When I go to the auction houses, I look for really big framed pictures. Usually when they come into the auction junk lot area, the art work is not very good, so don't fell bad about pulling it apart. It doesn't matter what color the frame is since I can paint over it. I liked the way this frame was so I left it as is. It's helpful if you can find framed art with no glass. One less thing you have to get rid of. It does take some time to fit the fencing into the frame.
