Many people made up Truth in Advertising, and they didn’t necessarily know each other. Bob Stayton, aka “William Board”, invented the method used by TIA. The first billboard was done with his housemates as a weekend project. They discovered it was so much fun that they told friends, who then told other friends, and a clandestine network developed.
No one knows how many people participated over the years. There was no roster, and no email list (there was no email back then). Since the activity was illegal, it was best not to know names. Subgroups would coalesce into a billboard project, and would draw on others in the network. The billboards pictured in this exhibit all involved Bob Stayton, who photographed the work before and after.
