I'm always on the lookout for artifacts of graphic design. For example, I just ran across a catalog of Presstype materials from the early 80's. I've never produced any design work outside of a digital world - so it's a great way to appreciate just how much work went into the projects produced by my predecessors.
You can imagine that I was pretty excited when a friend of mine passed this little booklet along to me after his trip to UK surplus: "FACTS about the University of Kentucky."
