This is a scan from a glass negative I recently acquired.   It's an image of Porterville's Red Cross Chapter during World War I  (1917).   This office was in the upstairs of the Putnam Pioneer Store on Main St.      The photograph is by Hammond Studio of Porterville.

(Added 12/15/13)  This appears to be another view of Porterville's WWI Red Cross Chapter in the upstairs of the Putnam Pioneer Store.   I count about 120 workers here.   The sign at the lower right side states:  "Visitors are Not Admitted.   Only workers with cap and apron allowed in Surgical Dressing Dept.     All workers must wash their hands before working in surgical dressings".         This is a scan from the glass negative which has unfortunately suffered a lot of damage,  which limits the view somewhat.

 Photograph by E. M. Davidson of Visalia.   Written on the back of the photo:  "Lilburn Dunn,  Clara May Dunn   (Center)  Wedding Picture".   And with a different pen someone has written "Father" and "Mother" next to the Dunn couple's names.   Tulare County marriage records list a Lilburn Dunn and Clara M. Hilliard marriage on  4/23/1890.

Photo postcard of Porterville, CA,  circa 1910.   The photograph is by George Besaw  (Western Postcard Company).    This photo was taken looking north on Main St., between Oak and Mill  Avenues.     The Putnam Pioneer Store (mentioned with the Red Cross photo above) is the building here with the two pointy roof spires.
