Perhaps it's already common knowledge but a standard business card is the same length as a standard playing card. While that may not seem all that exciting to some it opens up some pretty cool gift ideas. The most creative I saw was at PokerGiftIdeas.com to use a card shoe (like the ones they deal Blackjack with at the casinos) as a business card holder. I tried it myself and it's pretty cool. It does work better with smoother business cards (it works great with the picture ones) as they are more like playing cards. Fancy business cards with the raised lettering are a little harder to get out but it works and it still looks cool on your desk. It's also a nice way to 'advertise' your card playing interest at work and fill up empty seats at you Friday night poker game.
