Here is an awesome vintage jersey by Venus Athletic Wear. 50/50 poly and cotton blend, and made in the USA. Could be from the 70's, but I'll say 80's. Dark blue shirt with light blue and white accents. Slight Vee neck. Medium weight to this one. It's in amazing shape, and has years of life left. The tag says 46-48, but here are the measurements. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 23"
Shoulder to end of sleeve (including cuff) 9"
Length 32"

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