This work, entitled City Art 20, is a 1970s photograph by New York/San Francisco photographer Roz Joseph (1926-2019). Joseph traveled extensively through Europe, North Africa, and Asia in the 1960s shooting in black and white and processing her silver gelatin prints in her own darkroom in New York City. In the 1970s, Joseph moved to San Francisco, began shooting color film, and started an architectural abstract photography series she called City Art. In 1991, Chronicle Books published a book of Joseph's architectural photography entitled Details: The Architect's Art. Joseph was also known for her extensive archive of photos exploring San Francisco's early drag scene.
