ARTIST TRADING CARDS are miniature works of art created on 2 ½ x 3 ½ inch or 64 x 89 mm card stock.
They are originals, small editions and, most importantly, self-produced. anybody can produce them.
The idea is that you trade them with other people who produce cards, either at TRADING SESSIONS or wherever you meet another ATC trader in person.
There are monthly TRADING SESSIONS at different places (zürich, calgary etc.)
The project was initiated in 1997 by zürich artist m.vänçi stirnemann. since then several hundred people from all over the world have traded ATCs during TRADING SESSIONS, through mail or by participating in COPY-LEFT EDITIONS and SISTER TRADING CARDS (STC).
