This Fuji branded film is a clone of Ilford XP2 Super.

This is the door of an old motel to be demolished. A group of police canine units was using a nearby building for practice drug raids when one of the dogs pulled its handler toward this motel, and indeed they found and arrested some very foolish people using the motel room to package illegal drugs. So it may be a police boot-print... Conveniently, the jail is right across the street.
