This is a nice vintage Performance jersey from a simpler time, before jerseys were turned into traveling billboards.  There are a couple faint stains and pilling in the fabric, but it is overall, in very good condition, considering its age.  It are still plenty of miles left in it.  The zipper is in excellent working order.  I cannot locate a size on the jersey, but it fits like a Men’s medium. See measurements below for best fit: 

Chest (underarm seam to seam):  21”

Shoulder seam to seam (across back):  18”

Shoulder seam to end of cuff:  9”

Neck seam to hem (in back):  28”

Side seam to seam (across hem, at rest):  18”
