A 4x5 transparency of the yellow brick Sing Chong Building at the corner of California St. and Grant Avenue in San Francisco's Chinatown; a vertical neon sign advertises the Cathay House restaurant on the corner of the building. The view looks down Grant Ave. and encompasses dozens of signs, streetlamps, storefronts, and pedestrians. Paper lanterns and red banners with golden dragons are hung above the streets. To the right is Old St. Mary's Cathedral. Handwritten on the envelope: S. F. China Town
