Not sure of the year/era on this one but definitely vintage. Made in USA by Red Oak. 100% Polyester. There is some mild "cracking" on the front graphic so please see photos.
Tag says it is medium but hockey jersey sizes can be weird depending on whether someone is wearing pads underneath or not. Please refer to measurements below:
25.5" long from bottom of collar on back to bottom of jersey
22" armpit to armpit
