When you work mainly with recycled materials like I do, once in a while you find a little surprise. For my map/travel journals, I recycle bookboard from unwanted books for the covers. Sometimes I pick up a few covers at my local ArtsJunktion, a place to pick up some great supplies for free! They have stacks of book covers with the insides already removed, like these:

My guess is that the person who made that navy bookcloth was a recycler too, and used some advertising posters as the backing. Isn't that hilarious?
