There never was and probably never will be as they are the only NFL team without a logo.
The Clevland Browns still do not have a logo on thir helmet
The Steelers logo is based on the Steelmark logo belonging to the American Iron and Steel Institute (AISI).
They just wear an orange helmet.
The following web site: www.packersuniform.com states that the now iconic "G" helmet logo was first used by the Packers in 1961 (designed by equipment manager Dad Braiser). The University of Georgia began using the "G" helmet logo in 1964. Grambling University (Louisiana) began using the "G" helmet logo in the early 1980's
In 1962, the Steelers equipment manager Jack Hart applied the logo to the helmet (at that time the helmets were a solid gold color) and the Steelers were uncertain how it would look. So he applied them to the right side only. Later on, even after changing the helmet color to black, they left the logo on the right side only, due to the teams new found success & uniqueness of the logo. The Steelers are now the only team with a logo on only one side of the helmet.
