File:United States Aeronautical Reserve and USA military officials, group photo, 1910.jpg

Summary
This 1910 United States Aeronautical Reserve military photo is under USA government jurisdiction because it would have had to be approved by the military of the USA government at that time in order for it to be printed in any publications. It is possible that there are several semi-private copyrights on photo, but they probably expired and are probably not totally valid because of it actually being under US military, US government jurisdiction.
