Here is an awesome vintage T-shirt. I can't quite make out the tag for the brand, but it's 50/50 cotton and poly blend, and made in the USA. Royal blue shirt with wonderful Snoopy and Woodstock New York Giants graphic on the front. The last listed copyright is 1971. Thin, light, super soft and comfy. It's in amazing condition with tons of life left. 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 26"

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