The Keebler Elf was first introduced in 1936 as part of the "Famous Forgotten Characters" series of advertising mascots. The Keebler Elf was initially intended to promote Keebler cookies and crackers. The Keebler Elf was a successful advertising campaign, and by the 1950s, the Keebler Elf had become a cultural icon, synonymous with the Keebler brand. The Keebler Elf is known for its mischievous personality and love of baking and cookie-making, making it a perfect mascot for the Keebler brand.
