Vintage BMW Rally T Shirt by Belton

Here is a super cool vintage t-shirt from the 80s by Belton. 100% cotton and made in the USA. Yellow shirt with great graphic on the front. It's light weight, very soft and comfy. It feels like it's never been worn. It's in excellent condition with years of life left! The tag says Medium 38-40, but here are the measurements taken laying flat. (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 28"
