Artist Trading Cards are business card-sized works of art that are traded (for free, never sold) with other artists. A fellow babbler, AprilD (where are you, April?) mentioned these in passing the autumn of 2006, and the idea took off from there.

A couple sites that give great introductions to these little gems are:

• www.ebsqart.com (has lots of examples of other peoples’ work)
• www.cedarseed.com/air/atc.html (more ideas and some explanations)
• artist-trading-cards.ch, the original ATC artist’s site (in English)
