Heavy use is evident throughout this practice t-shirt worn by Pittsburgh Steelers Hall of Famer Jack Lambert, and it originates from his personal collection and comes with a signed letter. Dated to the mid-'70s Steel Curtain era, this black top has Champion size XL tag in collar, XL box tag on front tail, and the material is similar to that of jerseys of the era. "PITTSBURGH STEELERS" is screened in yellow above and below a yellow football with Lambert's number 58; this was worn during workouts and team practices and the extensive crazing to the screened portions only adds to the overall look. Lambert's tenacity from the linebacker position was a key component to four Pittsburgh Super Bowl titles. Comes with LOA signed by Lambert.
