Gilt Gesso? picture frames help with age?

Hi all, i posted these prints on the art board a few days ago but would like to find information on these frames.
If anyone could tell me approximately the age of these it would be greatly appreciated.
They measure 10 1/2" x 12 1/2" and look like plaster on wood.

Hard to say. Maybe as early as the 30s but could have been made the same way into the 50s.

 

Thank you very much Brad. at least now i know something..
