2.75" oval with metal back and bar pin plus curl text of maker Phila. Badge. Front is artwork by class student although they acknowledged their use of the characters by including in small text on the rim edge "Walt Disney Prod." Bold text reads "Class Of June 1942" and captioned beneath each duck are the names "Huey/Louie/Dewey." Couple of long but very faint and light hairline scratches show only in reflected light. Button displays Mint and is the only example we've seen.
