I’ve seen these before and they are definitely the most unique business cards I’ve ever seen.
We got this business card LEGO person from LEGO Universe Creative Director Ryan Seabury yesterday, and every single person we have showed it to since agrees that it is indeed the best form of sharing contact information ever seen. Seabury’s name and likeness are on the front, and his phone number and email are on the back of the little guy.

That is pretty awesome. Although… it would get hard to carry around more than a couple of these little guys in your pockets, and they wouldn’t fit in your wallet at all! 🙂
