This guy’s a dude. Note the scarf tie, popular in the 1920s. Driving cap in plaid, striped shirt. Sleeves rolled up. Good shoes. Odd expression, but photography was still new then.
I haven’t a clue as to where this studio photo was taken. However, it’s a Real Photo and the AZO square (on the back, upper right) with two triangles pointing up and two triangles pointing down indicates that the photographic paper was made between 1918 and 1930.
You go, guy.
