Painting

The Hidden Tiger

The Tiger's stripes spell out the title of the painting.

Dream

The outline of the barn door, an old tire, some chicken wire, and other items make the shape of an old jalopy. 

Ten Friends

The missing "friend" is a Zebra hidden in the garments and shapes of the six figures on the left.

Deer

The trees and branches above the deer form the shape of a large antlered buck.
