This is just one of the many team signed baseballs from the "Ian Duff Collection" that we will be listing. Duff was the visiting clubhouse manager for the Toronto Blue Jays for 14 years (1981-1994) and obtained the signatures directly from the visiting ball players. Many of the balls have LOA's from PSA while others come with LOA's from Premier Auctions, the company chosen by Duff back in 2007 to broker his collection.
