A cavalry officer poses for his portrait at an unknown studio in an unknown location. This handsome military man is wearing what appears to be riding gloves and a sword in a sheath on his belt. He also has a belt buckle which may provide some additional information. However, limited magnification availability has precluded uncovering further identifying information on the buckle. It is unlikely that the subject is a member of an American cavalry unit. There is an embroidered crown on his left sleeve which may indicate he served in a Canadian or British mounted brigade. Another possibility is that the subject is actually an actor wearing a theatrical costume. Hopefully, a cabinet card visitor will leave an enlightening comment concerning this man’s identity.

It’s hard to think about where this soldier came from when I am so distracted by his enormous gravity-defying mustache.
What an image! I think it is probably an actor.

The sword and buckle seem to belong to a masonic or similar order. It may actually be regalia rather than uniform.
I believe it is Knights Templar.
The belt buckle and sword are Knights of Columbus.
