Here is an awesome vintage t-shirt by Screen Stars. 50/50 cotton and poly blend, and made in the USA. Light blue shirt with amazing iron-on graphic on the front. It's very thin and light weight, and super soft and comfy. It's in excellent shape with tons of life left! The tag says Large, 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) 8"
Length 27"

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