For years, salesmen have handed out business cards, collectors have exchanged sports cards, and amateur radio operators have sent each other QSL cards. One would expect that artists might eventually invent a better product that was individually creative.
So, the newest wrinkle is now Artist Trading Cards. There are only two absolute rules: The size must be 2.5 x 3.5 inches, and they must be traded freely, without cost. Any artistic medium is permissible. ATCs are optimally exchanged in person, so that a new friendship results, but there are also digital trading cards that are swapped via the Internet.
Kristin prefers the old fashioned style made with rubber stamps and photographic prints. We were all pleased with our "priceless" gifts and took home custom-made mementos of a delicious meal.
