This was an unusual order from a customer as it is a copper printing plate with a copy of the printed material, which is a wedding invitation to the customer's wedding. Each side had an inner slip frame then a oak 'cathedral' profile was utilised for the outer frame. The two were hinged together using brass hinges.
The back of the frames had a removable back so the plate could easily be removed when it needed cleaning and polishing.
Turnbuttons created a neat and strong removable back to the frames.
