It's driving me crazy. I can't figure out what that means. Anyone?

Artist Trading Cards.

HTH!

They are about the size of baseball trading cards and some collectors of ATCs use baseball trading card plastic sleeves to display them in.

At our local scrapbook store there are several who are into ATCs. They made a bunch just alike and trade with other people who love to make them.

They have some beautiful ATCs that the traders have made. My understanding is that they are just for trading.

They are traded a lot in local swaps and by mail.

Thank you both! It was like a puzzle I couldn't solve. Been driving me crazy for days now. Looked all through the site for a definition without any luck. When all else fails - ask.

I'm glad you asked because I didn't know what ATC stood for.
