This was a very unexpected pickup but I believe it's an autographed, game-used Bauer One 75 from Pavol Demitra during his time with the Canucks. Looked up some of his other game-used stocks online and the taping/signature look pretty close.
Looks very consistent with the other Demitra sticks I've seen; down to his kids names written on the shaft. The Canucks store sold these for $10 or $15 once he left the team.
