Mike Walton Toronto Maple Leafs Mattel Wizzer Card

Selling my Michael Walton Very Rare Wizzzer Toy Promo Hockey B&W Autographed Flyer 1970. I got this as a kid at a promotion giveaway when Mike Walton was hired by Mattel to sign these at Shoppers World Eaton's Store in 1970 to promote the Wizzzer Toy by Mattel. Very Rare and only a few that I know still exist.
