Why Don’t Fast-Food Companies Have Collectible Glasses Anymore? | Eater
"A major fast-food chain produced collectible promotional juice glasses in the early 1980s tied to film releases, including a 1981 promotion for The Great Muppet Caper that featured a Miss Piggy riding a motorcycle glass; these free-with-meal pieces are highly nostalgic, often sold cheaply at thrift and antique shops, but many vintage character glasses may contain lead- and cadmium-based paint that can leach into beverages and make them unsafe to use." - Amy McCarthy
