Frank Jump has an interesting project photographing vintage advertising murals.

Fading Ad Campaign is a photographic project documenting vintage mural ads on building brickfaces in New York City spanning nearly a century. It has become a metaphor for survival for me since, like myself, many of these ads have long outlived their expected life span. Although this project doesn't deal directly with HIV/AIDS, it is no accident I've chosen to document such a transitory and evanescent subject. Of the hundreds of ads I've photographed, many have already been covered up, vandalized, or destroyed. But still many silently cling to the walls of buildings, barely noticed by the rushing passersby.
