 The throwback gold helmets have often been worn in practice in addition to the regular black helmets, a highly unusual move among NFL teams whose throwbacks use a different helmet than their current design.For the 2012 season, as part of their 80th anniversary, the Steelers wore horizontally-striped throwback uniforms inspired by the 1934 Pittsburgh Pirates football team.The Steelers wore the throwbacks for their October 28 game against the Washington Redskins and for their November 18 game against the Baltimore Ravens.
