Where do Hidden Mickeys come from?
In the studios early days, Disney animators would famously insert hidden characters, messages or caricatures of friends & colleagues into many of the studio’s cartoon shorts, movies and features. The practice followed many of the fun loving artists to Disneyland, who began to incorporate their own secrets into the attractions.
Walt Disney Imagineers originally created Hidden Mickeys as inside jokes, then began hiding Mickeys in and around the Disney Parks and attractions. Since then, Hidden Mickeys have grown to become a popular part of everything Disney.
