[Update: This photo is identified on the back as a Universal western from 1915, with Arthur Allardt, Otto Meyers, “Ross” and Joseph Franz and apparently ran in a Midwinter Edition that wasn't microfilmed. The date of publication is stamped on the back but only the day, Jan. 3, is legible. According to imdb, Allardt and Franz appeared together in quite a few movies in 1914, but only three also have Meyers.  The candidates are “The Fight in Lonely Gulch,” “The Sheriff’s Story”  and “A Frontier Romance.” Meyers (later Meyer) had a long career as a film editor, according to imdb. ]

I’m not sure how this print ended up with all the film production photos, but here it is, weird cropping and all.
