Hi, I don't know what happened but I don't see the post related to the pic I posted. So here it goes again. My friend was at an estate clean-out of an old building that is coming down on the northside of chicago. He salvaged 2 VERY old picture frames that look like cages. They were very sooty and we cleaned them the best we could. Unfortunately, one of them had a print in it , but it disintegrated. It was a print of a painting of a lion lying down. It looked like an image of a lion that was from the 1800's. Long curly locks. The frame is roughly 3' x 4' and is solid oak, including the fake hinges. There are copper tacks at the top and bottom of each bar, made to look like rivets. I've searched everywhere on the internet but can't find a thing about them . One collector said that it's not something that someone would have hung in their home. So we're thinking that perhaps they came from a zoo. Lincoln park zoo is not far away from here. Any help on these would be greatly appreciated. As always, Thank you all.
