The grey tunic looks German WW1 (Bavarian Artillery?) but the insignia on the hat looks like the Panzer division.

The logo looks like the bottom part of the Heer Panzer insignia (without the Nazi eagle, above).

I note that the guy in the foreground is wearing a gray suit, but the hat is green.

Definitely prop stuff.

One of the things that I find amusing about Internet "found historical photos," is that women are usually made up with modern styles. I would not be surprised if they were originally done as fashion shoots, like this one.
