I always begin designing a corporate identity package by working on the business card first. I love the challenge a business card can present. Traditionally it's just 3.5" wide by 2" high. Then there is the space needed for the margins (and thumbs!) and ALL that text the client wants/needs on it. But, if you imagine total freedom within the space that is left - well then - there are no limitations really :)
My students often complain about the "restrictions" I give them on their assignments. To a professional designer they are the norm. I can only laugh when they say things like "but there's not enough room for all that" - I then pull out a business card I made several years ago for a client. It has three doctors names, two separate offices locations with addresses, phone and fax #'s along with the license number for each doctor, it's single-sided, one color and...wait for it...the client was an optometrist! Now mind you, though this card in too outdated for my portfolio, it still comes across as clean, easy to read, has white-space for the eye to rest and boldly defies the statement "there's not enough room."
I love the "restrictions" we have as designers. What fun would it be if four-color printing was so cheap that we never challenged ourselves to produce an amazing-outside-the-norm one-color design? A business card being a prime example. You (and I) can get full color BC's printed online at insanely wonderful prices! But that does not mean that every BC I design should be full color. It also does not mean that I shouldn't take advantage of those prices though when I need to print full color cards :) I'm just sayin'!
So, in my humble effort to raise a banner of independence for the business card I direct you to this amazing source of business card images that have been compiled on Flickr. Almost everyone of them screams at me "I'M AN INDIVIDUAL!" The designers have embraced the "restrictions" and created within that 3.5" x 2" space something that is indeed "be-you-tiful."
P.S. Offset printing cannot be beat - stop whining and pay the extra.
