When is a Horse Not a Horse?

For the Horsin' Around event, a number of people carved different images for a series called "When is a Horse, Not a Horse?" You could look on the event page for some of the other interpretations of this theme. For mine, I carved 5 different stamps. See if you can guess what they are (no fair peeking first):

1 1/2" x 2 1/2"

2 1/4" x 2"

1 1/4" x 2"

1 7/8" x 1 1/4" (bonus points if you figure out both answers)

2" x 1 3/4"

Some of these stamps will also be up for adoption, either together or separately, after they come home from Cherry Valley.
