Vintage 1980s Pan Am Plastic Button Pin for Unaccompanied Minors Pinback Badge

This is a vintage 1980s Pan Am button pin that has the airline industry standard on it that identifies an unaccompanied minor. This button is made of plastic - you sometimes see the metal versions, but these plastic ones appear to be less common. It measures 2 1/4 in diameter and is in good condition with a bit of scuffing and some soiling/discolouration - looks worse in the close-up photos than in real life. Despite the condition issue, this is a nice Pan Am collectible.
