7/8” plus brass wire which allows attachment to keychain and also allows the center celluloid enclosed in brass frame to be rotated. One side shows “Duroy Brand” product bottle with text for company “The Duroy & Haines Co./Soda Fountain Supplies/Sandusky, Ohio.” Reverse side shows woman holding up a glass while 3 product jars, probably containing syrup, are in the foreground. Text is “Not Made By A Trust/’Neither Am I’.” Trivial loss of luster from the brass. Celluloid areas are essentially Mint. Only example we’ve seen.
