Matchbook Art Drawings

I'm not sure why this popped in my mind within 15 minutes of waking up this morning (maybe I had a dream or something about it) but I was remembering those old matchbook covers that had drawings on them, usually of a turtle, pirate or donkey. You would draw it, send it in and see if you were good enough to get into art school or win an art scholarship. My brother and I always drew these. We were pretty good too - I don't recall us ever mailing them in but we were always glad when mom brought home one of those matchbooks.
