Get off the train and go to the luggage cart. Look at the trash can. This is eye level for a 5 1\2 footer. (In Storybook Circus, stroll to the exit of the WDW Railroad Train Station and locate a pile of tubs, trash cans, and luggage. The lower of two silver trash cans sitting upright has some suspicious indentations near the top of the can?)
Before you enter the shop, look to the right in the rocks. He is hard to see! (In Frontierland, depressions in the rock wall to the right of the entrance to the Briar Patch store might look like a classic Mickey. This image is difficult to photograph.)
What do you think of this image at the Star Wars Launch Bay in the Studios? Above the left side of the large metal door in the "Wookiee on Base" Meet and Greet area are three black smudges that might make a sideways classic Mickey.
A classic Mickey image is in the rocks (one large rock for the "head" and two small rocks for the "ears") embedded in a short wall to the left of the entrance to the Big Top Souvenirs shop in Storybook Circus. It's just below the top cement sitting surface and under the post with the red and blue base.
On top of the Il Bel Cristallo decorative pattern at the top of the building. (Along the edge of the rooftop of the Il Bel Cristallo shop are these designs. Do the three circles at the tops of the designs form classic Mickeys?)
