Ever wonder whose looking? At your stuff? How

Sometimes I wonder if people might be checking out my stuff. Unless people come up and tell you, which a few have in the past. Most of the time no one knows. When I was doing shows in Arcata, had my fish tank of hanging sharks and various fish. This was right across the street from Hensel hardware. Upon closer inspection of the big window outside revealed some interesting info. It was chock full of nose and forehead prints imprinted into the glass. That was our check of who was looking at stuff in the gallery. No other windows displaying art had these nose and forehead prints. Amazing the stuff you find!
