The absolute oldest toys produced by Fisher-Price originated from their introductory 1931 product lineup known as the "16 Hopefuls," which debuted at the International Toy Fair in New York City. Headlined by a whimsical, talking wooden pull toy named Dr. Doodle (alongside companion pieces like Granny Doodle), these early playthings were constructed of durable Ponderosa pine wood decorated with colorful lithographed paper and mechanical clicking sounds designed to entertain young children.
