First let me say, awesome jersey! And second, if you want to let it go I’m happy to take it off your hands.
Regarding the jersey itself, Lysiak played for the Hawks from 78-86 and this jersey lines up for that era. The tagging matches what should be 82-83 as Gunzo’s tagging on the hem didn’t appear until the playoffs of the 81-82 season and for the 83-84 season the hem would have CCM branding.
If you haven’t stumbled upon this resource yet, I’d highly encourage you to read it. Lots of amazing details in here:
