They are also hidden in architecture and attractions in Disney parks and resorts, and in studio buildings and many other Disney-related features.
[4] The history of Hidden Mickeys can be traced back to when the Imagineers were designing Epcot in the late 1970s and early 1980s.
The Disney Company had decided that EPCOT Center would be a more adult themed park, including selling alcohol.

Hidden Mickeys (as well as other Disney characters like Minnie Mouse) have become a staple of all theme park designs since.
