concept of ATC is the person-to-person trade, as well as trading by mail.
the most fun is to trade person-to-person though. the basic idea is the
card-for-card trade. [although
sometimes some people think one from their cards is worth more than one
from the others - mostly with the argument that they put more work into
WHERE TO TRADE YOUR CARDS
so far there are two ATC centers which organize Trading Sessions on a
regular basis: one in zürich and one in calgary. the idea of the
centers is not the private collection (there are many of those around
of course) but the communication. the centers are open to the public and
they also organize the ATC Trading Sessions. the centers are places to
communicate the idea of trading cards and to hold the events.
hopefully there might be more centers soon : ANYBODY CAN ORGANIZE A Trading
Session. the only stipulation is a certain continuity (eg. every month
on a regular day).
the different ATC centers inform each other as much as possible - so we
can exchange ideas and experiences.
