Vintage Red River Sweatshirt from 1983

Here is an awesome vintage sweatshirt from the 80s. 50/50 poly and cotton blend, and made in the USA. Magenta fabric with rad Red River (New Mexico?) skiing graphic on the front. Copyright 1983. Fairly light weight, thin, and incredibly soft and comfy. It's in amazing condition with tons of life left! The tag says Small, 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) 22"
Length 21"
