Here are some samples of rubber stamps carved out of plastic erasers, stamped and then scanned as images.
This one's based on the David refrigerator magnet I received for my birday. I think I spend too much time in front of the 'pooter.
These stamps are based on paintings on Ecuadorean pottery shards, circa 1000 A.D.
I designed and carved this linoleum block print for a Valentine's Day card. eheh.
