According to Chaplin collector, Shunichi Ohkubo the photos I posted yesterday were evidently taken by Tom Bones, who was a photographer at the Keystone studios in those days. There was some speculation as to whether the photos were from the time of the filming of The Star Boarder but this might not be the case (Bones also took some photos of CC & Minta Durfee from that film). Dominique exhaustively compared Chaplin's outfit (right down to the white tip on his cane) to practically every Keystone film and the only one that matches every detail is Those Love Pangs. The only element that isn't clear is whether he is wearing a striped shirt. Chaplin also has the watch chain attached to the safety pin. This was something that was missing from Getting Acquainted, plus the fact that he was wearing a striped tie. TLP was filmed around mid-September 1914.
