Large gold metal Rococo? frame with bubble glass and a tin back. Glass/picture size is 14" x 20". I am looking to find out if it is American or European. Early 20th or late 20th (1970s?) and how I could tell that in case I come across something like this again. I am really looking to learn. Thank you so much in advance for any help.
