Custom made for Jack and other Steelers' before the Super Bowl by Adidas, this fine example was worn by Jack during the days before the Pittsburgh Steelers victory in Super Bowl XIII. Truly unique piece sources directly from Jack Lamberts personal collection and has been in his possession since day one. All white Adidas warm-up suit with baby-blue stripe is complete with "adidas" embroidery on the left breast with "Super Bowl XIII" screen printed on the right breast and across the back in dark blue. One-of-a-kind memento retains all manufacturer's Adidas Ventex tagging in the collar along with "198/6,6"" label. Matching pants feature the same Ventax tagging with "198/6,6"" label. Suit shows light use and has been signed and inscribed "HOF '90" in black by Jack on the verso. Some light staining noticed.
