Recently I restored my infatuation with Artist Trading Card (ATC) by signing up a few ATC swap at Swap-Bot. What is ATC? Read it here : very thorough introduction to ATC.
Here are some of my previous ATC, made by me, for my own pleasure and collection. Back in my hometown, I have a few more dozens of ATC sent to me from other artist. I am looking for a way to store them, but they are slightly larger than business card size, so I can't keep them in business card file. Right now I just tuck them away in my craft drawer, some inside metal boxes, some became my bookmark.
