 The Steelmark logo itself has actually been heavily redesigned since then, using two variants, one of which uses a more modern design and uses three shades of blue for the astroids while another one used concurrently has a strong resemblance to the recycling symbol.One alternate variation the team used in the 1980s—though rarely used today—combined the logo with the team's signature stencil-script typeface, replacing the regular "Steelers" typeface used with the team's longtime script logo.The Steelers are the only NFL team that puts its logo on only one side of the helmet (the right side).
