This is a glass plate (2.5 by 3.5 inches), reverse-painted souvenir of Luna Park on Coney Island. Not sure of the year, but it's early! The buildings were originally painted a bright gold, most likely. There is some paint loss, but I put it on a white paper to show as much detail as remains. Still quite charming, and all the lettering is still there. It's in a frame to protect it. US postage will be .
