Ernie & Bert's Delivery Service is a 1983 Sesame Street board book shaped like a delivery truck, with rubber wheels at the bottom of the book that turn. The book was one of several toy books produced by Random House in 1983. The publisher also released a second "wheel book", Lowly Worm Car and Truck Book, a floating Care Bears book, and Hide-and-Seek with Wilma Worm, which had a magenta yarn bookworm threaded through the pages.
