The graphic visual environment of Los Angeles and southern California, with its advertising hoardings and architecture of neon signage, provides Ed Ruscha with ongoing source material. The prints in this series are based on drawings and adopt familiar sign and billboard forms. However, they are conspicuously vacant, drawing attention to ‘billboard’ signs in the landscape and their increasing obsolescence in this digital age. In recent years, Ruchsa’s work has been increasingly occupied with ideas of vacancy and voids, evident here where he exploits the unique qualities of the aquatint process to draw attention to empty surfaces.
