Tintype of lumberjacks or at least guys ready to chop wood.
Note the differances in the handles of the axes. I heard most those guys made their own handles to the scecs that worked best for them.
I would say that this pic is very late 19th Cen. or early 20th Cen. Most 19th Cen. handles were straight. Great picture anyhhow!! :D ;D
