Lots of small boys, and not a few girls, collect these during the AFL season. I created caricature/story cards of AFL stars and online activities for Teamcoach which, I hope, made collecting these a bit funnier and more fun.
The fronts of these cards were lenticular: if you tilted the card, the image would change to an action photo of the player. You could transform him back and forth by moving the card. I loved lenticulars when I was a little boy. Lenticular cards were as close as we got to smart phones 🙂
