The images on this page show the parapet at Sutro Heights. The stone parapet remains in 2020, though the observatory building and the statues are long gone.

Weidner Catalog shows eight Weidner 2 variants:
Charles Weidner was both a postcard publisher and a photographer, but most postcard publishers were not photographers (Behrendt: novelty store owner / importer; Britton & Rey: lithographers; Mitchell: businessman). Richard Behrendt published many cards with Weidner images (e.g., Golden Gate Park: Midwinter, City Hall, and Hotels: Palace Hotel), presumably under license from Weidner. Online sources suggest publishers played fast and loose with images during the decade, but I know of no concrete evidence for that, and most business records for postcard publishers are long gone. Later in the decade, Weidner certainly licensed images to other publishers, sometimes requiring a Weidner photo credit on the card. For example, Newman V187, Newman V195, Newman V198, Newman V201, and Newman V269 all credit "Photo only Copyrighted 1909 by Chas. Weidner" on the front.
In the first decade of the 20th century, the same image often appeared on postcards from different publishers, usually without credit. Each of these cards uses the Weidner 2 image with no Weidner credit.
