I'm no expert, so I can't date the uniforms or provide more information, but if you have any expertise please feel free to share. Appears to be a group of recruits posing before setting off for the war. Interesting to wonder what battles they saw and what became of them. Original mat is well worn as shown. For size reference, the frame is an 11 by 14.
