Corporate mascot of Planters Peanuts.
Mr. Peanut is a walking peanut with a top hot, glasses, and a cane.
As an aside, the Clinton, IA (motto: Armpit of Heaven) Mr. Peanut warehouse/silo has a huge Mr. Peanut on the side of it. As the story goes, sometime in the Seventies someone scaled the side of this very tall (probably 25 stories) silo and painted a fu manchu mustache on Mr. Peanut. It's still there today.
