The front should be glossier than the back, because it's a paper photo pasted on cardboard backing.

The fronts of all to nearly all reprints will have a printed dot pattern under strong magnification. Old Judges are actual photographs and photographs have no printed dot pattern. The images are made by exposing the photopaper to light.

Also, Old Judges sometimes have a bit a bow as your appears it might have. The bow happened as the card aged, because the type of photopaper used back then had a tendency to roll up with time. If the paper photos weren't glued to a cardboard backing, they often rolled up into a cigarette-like tube.

Last but not least, yours appears to have foxing (the brown spots) on back, which is a sign of old age.
