Left: Weidner 233, divided back. Right: Rieger, "The Californa Perfumer", b+w, undivided back; poorly printed (note the trailing ',' rather than '.' following "Perfumer"). These cards are based on the same image (note people in the same positions on 15th St. in both, for example). The Rieger caption is misleading/incorrect: the image looks east down 15th Street from Corona Heights (15th/Beaver), not Twin Peaks, on the second day of the fire (4/19/1906), not the first. The large stone outcropping at right is the Beaver Street Wall.
