Re: WWII photos
It sounds like the long picture is a Company picture that many units had taken either at a training camp or a later base such as at a Fort prior to being sent overseas.....A Battalion picture ( of which I haven't seen)would have nearly a 1000 men in the photo, but a company photo would have anywhere from 170 - 240 men depending on the type of company.
My father's Company picture for the 90th Div./358th Reg./Co.D was taken in Feb. 1944 by the Fort Dix, NJ photographer....a man named David Pond Willis....I have been unable to locate the negatives of the photos.
I recommend contacting the unit's Association if possible and see if any members of the unit have photos that could be copied.Good luck!
