r/askhistorians seems like the most appropriate place for this post, but if I am wrong I would certainly appreciate the direction to the proper sub.

I have been doing some light genealogy, and have stumbled upon an old photo that I have no references for.

Can you help me identify who this is? What kind of uniform is he wearing?

Here is the FRONT Here is the BACK

The writing on the back isn't any help to me, so even if a basic time frame can be gathered from the uniform I would appreciate it.
