This shirt appears to be Native American made and more than likely Iroquois. The leather is brain tan deer and the glass beadwork is typical of the tribe. It's in excellent condition with exception of two missing beads on the back (barely noticeable). The hide has the original bullet hole on the backside (shown in the photos).
Size: model is 5.11" 180 lbs and typically wears a size 42 or a large.
