MLB's Pittsburgh Pirates shared its nickname with an NFL team (which ultimately became the Pittsburgh Steelers) as well as a now-defunct early NHL team, while the Canadian football team Hamilton Tigers shared a team name with an NHL team. The most recent example of two major teams sharing a franchise name was between 1960 and 1987; when the NFL's Chicago Cardinals relocated to St. Louis, Missouri, it was allowed to keep the Cardinals name despite the established existence of a baseball team of the same name.
Logos and uniforms of the Pittsburgh Steelers appear on the front of the throwback helmets. The Steelers re-introduced gold helmets in 2007, paired with their 1962 throwback uniforms. The gold helmets featured the current Steelers logo rather than the original version of the Steelmark that was worn in 1962, and were also paired with black facemasks. These helmets continued to be used through the 2011 season. When the Steelers replaced the 1962 throwback with the 1933 horizontally-striped "bumblebee" throwbacks in 2012, the team retired the gold helmets. The Steelers have made only a few changes to their jerseys over the years. Originally, the team had vertically-striped jerseys
