This one is super cool...and good luck finding another one! Newton High School (Pleasant Hill, OH) sweater in deep red with white name and Indian logo on front left breast. 50% acrylic, 50% rayon. I'm saying 70's, but could be earlier. Super soft and comfy, with tons of life left! The size says medium, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 18"
Shoulder to end of sleeve (including cuff) 23"
Length 24"

This item is sold from a vintage boutique in Roanoke, VA.
