In regards to the first post, I just purchased an old frame and on the back there is a sticker or piece of paper. I have what you are missing, which is J.R. Webber Hardware or Moulding company. I googled it and found a great free e-book: The industries of Saint Louis: Her relations as a center of trade, manufacturing establishments and business houses by: J. W. Leonard
The part about this company is on page 89.
I don't know anything about your picture, but I LOVE my new frame I purchased for $20. Now to learn how to use this site and figure out how to contact the decendants of the people who I have their marriage certificate. They were married 10/31/1892.
