The world headquarters of the the Professional & Amateur Pinball Association are in Carnegie, PA, in one of the old industrial parks. This is the mural on the back of their building. This building used to be plain cinderblock and brick, and this colorful and professional mural is a welcome change. Even the Jersey barriers, placed there because vehicles would regularly misjudge the distance and hit the building, are painted with colorful images. I doubt anyone hits these things now!
