ADDENDUM: It has come to our attention that this jersey is actually a 1971-72 Danny O’Shea Jersey and not a 1972-73 John Marks Jersey as was stated in the printed catalog and previously on website.  

All original 1971-72 Danny O'Shea Chicago Blackhawks game worn jersey. Road red top has Wilson size 48 tag and Gunzo's tag in collar, both partially detached and very frayed. Blackhawks Indian-head crest is across the chest with crossed-tomahawks logo patch on each sleeve, white number 11 on both sleeves and back, and metal clip fight strap inside. Displays great use with some large team repairs and pilling.
