For business card geeks, like myself, there isn’t really anything greater than the club (society?). What they do is, well, collect business cards. If you never have, visit their site. Here is some navagational help:
Business Card Museum (a lot of World Trade Center business cards)
I know, their site does need some updating, but they don’t appear to be a “for-profit” type of club so funds are probably pretty low. Looking at their member list they don’t seem to be actively recruiting members either.
Check it out, it’s a good resource.
