This is an original vintage 1989 New Kids On The Block advertising fan souvenir pin back button. This is about 2 1/4 inch in diameter and is in good as found used working condition with a naturally aged patina. Look at the pictures and ask questions. What you see is what you get. I’m selling as is no returns. Check out my other auctions for more vintage stuff. I can combine shipping if mailed in the United States.
