This Apple IIc pin is cast in gold metal and printed with the 6-color Apple logo. The pin is 17mm square on a primarily red field. The font used for the words “The Apple IIc” is likely Univers 47 (Condensed Oblique), the font used in the Apple IIc’s marketing and on the computer’s keyboard.
The back of the lapel pin uses a protruding perpendicular pin with a butterfly clutch to secure the pin to clothing.
