I bought a King Cole photo in most recent RMY auction. Photo was likely taken April 8, 1914 at exhibition game with Brooklyn at Ebbets Field.
Questions:
1. Photo was described as Underwood & Underwood altho not stamped as such. Can anyone shed light on numbering system on upper left?
2. The photo was described as circa 1920 print. What might be evidence of this date? Cole was already dead 4 years. Why a new print?
3. does the horizontal orientation and size at 4x5.25 suggest a contact print? Maybe just trimmed.
4. The handwriting looks vaguely familiar. Any ideas?

In any event, it is a great photo of a good, short-lived pitcher.
