I see a lot of old wooden industrial molds but only occasionally do I across across ones like this, filled with a pitch/wood resin mold material, and used for casting ornaments for architecture, molding and picture frames. This is the smallest of several I'm listing, which photographs don't quite do justice (I've shot it a couple of different light situations to try to give a sense)--the mold itself has a really visceral presence, feeling like a cross between wax and tar, and the wood framing it is really beautiful. 

4 7/8" x 4" x 1 1/16". Early 20th centuryI believe and in excellent condition. There is a hook on the back for hanging, though I personally might opt to hang it from a different orientation, in which case the hook is easily moved.
