These were done for a PAT swap which means Pick-A-Theme. You sign up in a group of 5 players and each has its own theme. So, you make a card for each player in the required theme and you get back 4 cards each from a different player with the theme you've chosen. It's a great way to build up your collection of ATCs on a certain theme.
If you're an ATC artist or you're interested in trading ATC, you can join the ATCsforALL forum.
