A maroon-tinted 5x7 transparency shows a view of Market St. in San Francisco, looking northeast from just west of the intersection of Market and Powell Sts. The Flood Building is prominent on the left. Cable cars, automobiles, and pedestrians are abundant. It is possibly a holiday/holiday season, because many American flags and white banners with a red feather emblem are hanging over the street. Handwritten on the envelope: Market St., San Francisco
