Champion Spark Plugs sign as seen on a building in Kingston, PA. This place has a storied history, as it had formerly been a factory that made caps for kids' cap guns. (Citing the dangers of this, the town FD got an order for the business to leave town. Shortly thereafter, it exploded with much devastation at its new location!). Following that, an auto parts store occupied the space, until the owner's retirement. Then it became a pizza restaurant and bar, closing in 2015, again due to the owners' retiring. The building is now for sale.
This sign, obviously, is a vestige of the parts business. It is located on a wall visible to traffic, until a garage was built, occluding the view. And so it remains, as an indicator of one of its previous incarnations.
