This is a series of die-cut cardboard signs which slipped into the top of a pair of boots. This one is my favorite. The drawing of the guy is stylized in an interesting way. Check out his pleat front denim jacket. I've also always loved old surplus Willys Jeeps like this one.
This last one is the largest and unfortunately was trimmed by the store owner i got it from. He wanted to use it in a display of boots from another maker.
