This 6' × 24' graffiti mural is the work of Gamma Acosta, Longmont, Colo. "Crayons" is his statement about the Sandy Hook school massacre, done a day later. It's gone now, boards and all, to an anonymous art collector who wanted it preserved. Normally Acosta, who paints on his uncle's vacant building, would have painted over it to make way for his next mural.
