The Pittsburgh Steelers jerseys didn't change much in their glory days of the 70's and 80's. That lack of uniform change is one of the things that make this 1975 Steelers jersey stand out from the rest. With the United States celebrating the Bicentennial in 1976, the NFL got in on the festivities by having the two Super Bowl teams wear a Bicentennial patch in the big game. Those two teams were the Cowboys and the Steelers, with the Steelers winning Super Bowl X, 21 -17. Steelers QB Terry Bradshaw was 9 for 19 with 207 passing yards and two passing tds as he led the Steelers to their second consecutive Super Bowl title. This polyester knit jersey has engineered sleeve stripes, one color twill name and numbers, an embroidered twill American revolution Bicentennial patch and an embroidered felt player/year ID patch. 100% polyester double-knit body. Engineered sleeve stripes. Twill name and numbers. Embroidered American Revolution Bicentennial patch. .
