I was able to identify as a USAF plane from between the two World Wars, and while he is happy with that description, I'd like to give him more, as he is dedicating the shot to a friend who recently passed away.
Here is the image in question.
What I would like to know is:
Original use and purpose?
Did it serve in the war or is it a trainer?
The history of this particular frame, if possible?
Thanks a million, guys!
