Terry Crider signed Old Carnival Glass Marigold "Flower & Pleat" Tumbler

Description

Old Carnival Glass Marigold "Flower & Pleat" Tumbler signed by Terry Crider. Condition is "Used".  Notes with it said Rodenhouse Tumbler and Austrian but I am unable to verify those.
Terry Crider and his wife Donna began creating glass art in 1976. They sold their first pieces at flea markets. Terry had a chemistry background and he worked to develop a special formula for iridizing some of his glass. He made unique paperweights with each piece being 100% hand made and his unique iridizing formula resulted in many one of a kind pieces.
Item was purchased at an estate auction which had belonged to a former officer of a carnival Glass club who like to send old unique tumblers to Terry Crider to work his magic on.
Tumblr is about four and a half inches tall and two and a half inches wide.
