Here is an awesome vintage t-shirt. The tag is too faded to see. Feels like a 50/50 cotton and poly blend. Maroon shirt with white accents. The number 17 is stitched on the back. I can't even describe how impossibly soft and comfy this shirt it. It's in excellent shape with tons of life left! The tag says XL, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 22"
Shoulder to end of sleeve (including cuff) 9"
Length 29"

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