Left: Weidner 119, credit front bottom, undivided back; postmarked Los Banos 11/19/1907. Center: Weidner 119, credit moved to back, divided back. This is obviously a pre-quake image with added post-quake caption, but to date I have seen no earlier variant (without post-quake caption). Right: Weidner 225, post-quake; undivided back. The caption should read "Memorial Church", not "Memorial Arch"; Weidner 224 shows the post-quake Memorial Arch.
