BirdDog Press is a great collaborative design studio and collaborative print shop headed by Allie Bozeman based out of Lyons, Colorado. They have some great examples of business cards and posters, but I really love their cards. I love the ones where she uses eyelets to accentuate the design. The letterpress process has on form of dimensionality, and those add another! Don’t miss browsing through their website, shop and flickr page!
