Have you ever passed one of those 20-story painted billboards and wondered how someone created something so big and so realistic? There are maybe 50 to 60 billboard painters left nationwide, and half being over 50 years old. Find out in Episode 2 about the art of billboards from Tait, one of the country's few (and younger) remaining mural masters. "I think I've painted over a million square feet of murals," he estimates. "I mean, at times I've painted buildings that are 220 tall by 100 feet wide, so what? That's over 20,000 square feet right there."
