Here is an awesome vintage T-shirt by Sport T. 50/50 poly and cotton blend, and made in the USA. Light tan shirt with amazing iron on decal on the front, and "Jim" ironed on the back in velvety soft black letters. This one is thin, light weight, incredibly soft, comfy, and in amazing condition with tons of life left. Might be 1970's, but I'm calling it 80's. The tag says Extra Large (46), but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 20"
Shoulder to end of sleeve (including cuff) 7"
Length 27"

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