Fubiz has a post up entitled "70 Amazing Business Cards" and while I wouldn’t go as far as to call all of them "amazing", there are some nice examples in the list making it a good resource if you’re looking to make some for yourself. My personal favorites are the embossed style, I love that texture, it makes the card feel so much more substantial.
I have always been sort of torn on the subject of business cards. On one hand, I love the type-based examples, they’re so clean and to the point. But on the other hand, that doesn’t always say much about the work the holder of the card might expect to find on your site. For mine, I ended up settling on mini posters on each side with the pertinent info worked into the original poster designs, sort of a quick glimpse of my portfolio.
