This is an early ‘70s profile of a billboard artist in San Francisco.

Begins with a wide shot of the artist working on a creating an advertisement on a large billboard for Western Airlines. The billboard shows a woman relaxing on a seat, and its caption reads, “3 feet for your two legs. Jet Western to Minnesota." Note that Western Airlines was a major U.S. airline that operated from 1926 until its merger with Delta Air Lines in 1987. Close-up of the artist painting a sheen on the woman’s lips; his paint brush daubs the billboard with white paint. 

Inside a studio, a man is shown perforating a design, which has already been added to a large sheet of paper, with an electric needle.

Artists are shown attaching the above perforated designs onto a giant white billboard. They plan to use these designs as stencils for adding images to the billboard. The stencils ensure that the images are kept to perfect scale and have the correct proportions. The artists wipe rags over the perforated areas, perhaps to get the design or drawing onto the billboard.

We then see a the billboard artist on a scaffold painting part of the face of a man on the billboard; the artist uses a reference photograph to guide his painting.

In the final shot, a man paints a billboard with white paint in preparation for starting a new advertisement.
