Gaping Void, cartoons drawn on the back of business cards. New Yorker, Hugh Macleod, draws these as a reaction to life in the city. fun stuff, kind of not Sex and the City
Reminds me a bit of the Pink slip parties from 2001. At one of these events the bar collected old business cards and stapled them to the wall, I think they collected thousands, certainly I've got at least 4 or 5.

Don't throw any business cards away, I collect business cards. I would love to add any to my collection. I keep mine in binders and special sheet protectors made for business cards and often use others for the odd sized business cards. Send any business card(s) to:
