Burger Chefwas a fast-food hamburger chain that started in Indianapolis in 1958. At its peak in the mid 1970s, it was second only to McDonald's in the number of nationwide locations. The late '70s saw the introduction of animated spokespersons Burger Chef and Jeff. In 1982, the chain was sold to Hardee's who gradually converted stores to that name with the last remaining Burger Chef closing in 1996. There was renewed interest in the chain when it was featured as part of a storyline on the hit TV series Mad Men.â€šÂ â€šÂ Click here for our tee with the updated logo from the late '70s.
