Yesterday was the one month anniversary of my latest employment. Two days prior, a marker for "now you are really part of the company" arrived at my desk: new business cards.
Business cards here are not a small production. The front of these cards do not immediately appear unusual. Gray sans-serif font for my name, phone numbers, and company name and address. The company logo and my company email address appear, each in a new color.
The cards themselves are on very heavy stock. Office legend tells us that this paper is handmade. A stack of ten cards is about 3/8th inch. These would crush the competition in a restaurant "drop in your business card for a free meal" fishbowl.
Flip a card over and you see one from a set of seven carefully selected colors. A reexamination of the card front reveals that the logo and email colors also vary from card to card.

So what, you're trying to entice all your old engineering friends in for an interview with the fancy new cards? Hmm. It could work. Trout are smarter than most of us...
