This City Hall image is © 1902 by Goeggel & Weidner (Class H XXc #18442 6/02/1902).
Charles Weidner and Richard Behrendt must have had a business relationship, as many early Weidner images appear on Behrendt cards, including this one, Sutro Heights: Parapet, Golden Gate Park: Midwinter, and Hotels: Palace Hotel.
