There are a few hidden mickeys that can be seen from the window of the Silhouette Studio.  One of more obvious ones is a classic hidden mickey in one of the small pictures.  However there is also another hidden mickey that is a lot smaller and harder to see.

If you look carefully at the large picture frame on the right you can see a classic hidden mickey in the decorations in the frames.  There is actually several different sized hidden mickeys in that frame if you look closely.
