Rin Tin Tin
One of the most popular items of the 1930's was Rin Tin Tin carnival clays, modeled after the early animal Movie Star and German Shepherd, Rin Tin Tin. which were distributed as prizes at the local carnivals and sideshows. Many Thousands of these were made and Awarded as Prizes, but due to their fragile nature, Few Remain Intact. Their name, "Clays" indicates something that might be more durable than just "Plaster of Paris," which is what they were molded of and contributed to their scarcity over time because the material is unsubstantial, soft, and lacks durability.
