When I was a kid, Dad was the partsman for the IH dealer in town. The owner also had a hardware store. Mom kept books for both places at that time and Dad would help out in the hardware as needed. One Saturday night, I was amusing myself by walking quickly along and running my hand over the tops of the front glass on those shelves that you were talking about. (The sections were held together by metal clips.) As I tooled along with my mind elsewhere, I came to a piece of glass that had a semicircle broken out of its top edge. Fortunately, blood cleans up quite nicely from glass and wooden floors.
