Hidden Mickeys Starting out as inside jokes by the Disney Imagineers in the 1980s, the subtly visible silhouette of Mickey Mouse began appearing in a few attractions in the Disney parks. Soon, park guests were having a great time trying to discover these “hidden” Mickeys, to such an extent that they were finding the common three-circle form in areas where it was simply a design fluke and never meant to be a Mickey shape.
