This is a Jacob’s brand teapot and mug set that was probably a giveaway with a purchase of the Jacob’s Cream Crackers. The design of the teapot and mugs was to reflect the distinctive look of the cream cracker. Such giveaways with purchases were popular in the late 20th century. Jacob’s Cream Crackers were sometimes consumed by children when they were sick as the crackers were perceived to be easily digestible, especially when dipped into a glass of milk.
