Each card has tiny graphic representations on blind deboss (ink-free) impressions — hammers for the contractor and electric bolts for the electrician. It was fun to get to work with these fellow craftsmen and small-business owners.
Speaking of growing a business: cards we did for Grow. These involved three custom letterpress inks on the front, offset flood and one letterpress ink on the back. They were hand-duplexed (two different paper stocks glued together) and edge-painted in a corresponding brick-colored ink. That sounds like a lot of press runs, right? Three runs just to make one side of this card! Oh, and, we did cards for 28 employees. Nothing says "we're glad you work here" than the boss handing an employee a box of beautiful, hand-crafted letterpress business cards.
