Vintage Troop 63 T Shirt from the 80s by Sportswear II

Here is a super cool vintage t-shirt from the 80s by Sportswear II. 50/50 blend of polyester and cotton, and made in the USA. Tan shirt with cute graphic on the front in green. It's thin, lightweight, soft and comfy. It's in excellent condition with years of life left! I'm guessing this is a child's sizing. The tag says Large, but here are the measurements taken laying flat. (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 25"
