Yellow head with stamp on tongue
A yellow, one-eyed head with a stamp on its extended tongue. I am not sure if this is a Minions reference, a drug reference, or something else.
The Graffiti Highway is a former alignment of Pennsylvania Route 61 through Centralia, Pennsylvania. This section of road was abandoned for a new alignment in 1993 due to ground subsidence caused by an underground coal mine fire that has been burning under Centralia since 1962.
