What was the name of McDonald's city mayor mascot introduced in 1971?

McDonald's city mayor mascot introduced in 1971 was Mayor McCheese.

Mayor McCheese appeared as a large cheeseburger-headed character wearing a suit, sash, and top hat. He was presented as the mayor of McDonaldland, the fictional world used in McDonald's advertising to connect the brand with a cast of playful characters.

The character was part of a broader branding system that included Ronald McDonald, Grimace, the Hamburglar, and Birdie. McDonaldland gave McDonald's television commercials a recurring setting and helped make the brand especially recognizable to children.

Mayor McCheese is sometimes mixed up with McCheese, a product name, or with the Hamburglar, whose role was based on stealing hamburgers. Mayor McCheese's defining branding role was civic leadership in McDonaldland.
