The Philadelphia High Schools had a tradition of picking an "unofficial" mascot for each graduating class. Simon Gratz High School chose the comic strip character Myrtle as their class mascot. Button was issued for the graduating class of June 1945. This was the first time that particular high school had selected a class mascot and joined all the other public high schools in the tradition. Issued in the school colors of red and white this button say limited production and was available only to members of the graduating class. A bit unusual as the name of the school is not displayed on the button.
