Ahtist Trading Cahds (ATCs)

In my copulous free time, I've gotten good and intimidated about making ATCs.
Some sites to look at when you think of your artistical trading cards for the next SANE meeting (23 March 2010):
http://www.artist-trading-cards.ch/ - this is kinda a clearinghouse of info, links. One active, one inactive swap (send 20, get back 15 different)
http://www.artist-trading-cards.ch/links.html - many links to many sites w/ ATC
http://www.facebook.com/group.php?gid=27062918329 - facebook site with lots of pictures (don't need to be a facebooker)
http://www.linesandcolors.com/2006/08/17/artist-trading-cards/ - Charley Parker gives a short history and "rules" about ATCs. I steal from him:

The general rules for Artist Trading Cards (ATC) are:
The card must be the size of a standard trading card: 2.5 x 3.5 inches (64 x 89 millimeters)
A card can be ether an original work or a very small edition
The back of the card should have a signature, the date and the number (if the card is part of an edition) and ideally an address for the benefit of contacting the artist for additional trading.
Techniques and materials can be almost anything: paintings, drawings, collages, photographs, rubberstamp works, mixed media, found images, assemblages, beadwork, woven, string, doctored existing trading cards, etc. The only real rule here is that the card should fit into the standard plastic album sleeves for trading cards, which leaves out anything too dramatically thick or three-dimensional.
The cards are not to be sold, only traded or given away. (This is a noble attempt to keep the practice non-commercial, but as with comic book artist convention sketches, that trust is sometimes betrayed; artist trading cards can be found on eBay.)
The cards should ideally be original, but reproductions or "editions" are permissible. There is some controversy about this, mostly centering around the failure of someone to be up front about the nature of the work when swapping.
There is also controversy about suspending judgment when swapping to avoid assigning value to the cards (the "quality" and amount of effort put into the cards varies wildly). Stirnemann himself has struggled with the issues of copies vs. originals and the suspension of critical judgment.
Look through the links on Stirnemann's site and do a Google search for "Artist Trading Cards". There are numerous forums and community sites devoted to the subject. There is a large Flickr group devoted to the subject with over 400 members and more than 2,000 images.
Community, and sharing art with others, seems to play a large part in the appeal of the practice. At the very least, it's a fascinating concept.

I'm confident that I can make cards 2.5 x 3.5 inches, but that's about it, so there.
