Truth In Advertising

Source : These billboards appeared on the streets of Santa Cruz, California, from 1980 to 1985. The billboards were made over by a clandestine network of midnight billboard editors operating under the name of Truth In Advertising, or TIA for short.

This exhibit of their historic work was first presented in 2007 at the Santa Cruz Museum of Art and History. http://sagehill.net/tia
