Boyd Crystal Art Glass Shoe Slipper Cat. Caramel Slag, yellow to amber with white swirl. This lovely shoe slipper has a Daisy Star pattern around the sides with the lace type pattern in the front of shoe with the cat head hanging over the edge of the top. Makers marked with a B in a diamond and a line over the top and bottom. From what I researched about the Boyd Crystal Art Glass Co, this marking is called the 3rd five year mark, which is from 1988 to 1993. John Degenhart started Crystal Art Glass in 1947 in Cambridge Ohio and his wife Elizabeth took over after is death in 1978. This Carmel Slag version is harder to find.
