This is my personal card. Whatever, it's mainly a way to give people my PGP key fingerprint.
This is my current card, since around July 2012. I needed a new one when I embiggened my PGP key. I got it printed on cream-colored paper.
This is my old card.
Don't get your business cards printed at Kinko's. They'll just run your design off on a copy machine and cut the cards to size. Your cards won't look like real business cards and they'll cost more, too. The magic word you want, for nice raised textured printing, is “thermography.”
I got my old card printed at Signal Graphics and my new one at PIP.
