The Steelers logo consists of three four-pointed astroids stars hypocycloids of four cusps, with the team name Steelers to the left, with a ring bounding them all. The idea behind the three stars is that “Steel lightens your work, brightens your leisure, and widens your world.” The three asteroids symbolize the primary colors and reflect the manufacturing process of steel. The colors came to represent the ingredients used in the steel-making process: yellow for coal, red for iron ore, and blue for scrap steel. While the formal Steel mark logo contains only the word “Steel,” the team was given permission to add “ers” in 1963 after a petition to AISI.

In 1962 a new logo was designed to show a yellow and black steel worker punting a football on a yellow steel beam. It is rumored that mascot Steely McBeam was based on this logo.

The Steelers first logo is a football with Pittsburgh’s then smoggy skyline, as well as a construction worker hanging onto a chain holding a pennant. A wordmark “PITTSBURGH STEELERS FOOTBALL CLUB” in black.

In 1944 the Steelers merged with the Chicago Cardinals and were known as “CARD-PITT” and informally known as the “Car-Pitts” or “Carpets.” The Steelers went solo again for the 1945 season.

In 1943, when manpower shortages stemming from World War II made it impossible to fill the roster, the team merged with the Pittsburgh Steelers forming the “Phil-Pitt Eagles” and were known as the “Steagles.” The merger, never intended as a permanent arrangement, was dissolved at the end of the 1943 season. The logo is a black eagle grabbing a black helmet.
