Apologies for the late post, this has come on my radar just now.
GameWornAuctions.net's Spring 2019 auction features two jerseys worn by Guy.
The first is a home jersey from the 1986-87 season, which is hammered with wear and team repairs. The current bid for this jersey is $707.39 USD.
The second is an away jersey from the 1989-90 season, during which Carbo shared captaining duties for the Habs with Chris Chelios. Therefore, this is one of Guy's first captain's jerseys. The current bid for this jersey is $855.94 USD.
Both auctions close on Tuesday, May 21 at 10:00 EDT.
