My choice isn't really a hair do, but more of a hat do:
This photo was part of my great-grandfather's papers. That's all I know. He was from Germany, so I'm guessing this is a relative back in the home country. My great-grandfather came to the United States in 1914.
I call this guy "Hat Dude." If anyone can shed some light on this uniform or its era, I'd really appreciate it. He seems very proud of his threads. I'd like to know more so I can share in that admiration.
