Pinpics #21790.  Description courtesy of pinpics.com:

Same design as Pin ##16692, 21791 and 21792, but this pin has a bright red background. The description given for Pin 16692 applies equally to this pin (I have had this pin since at least the early 1990s), except that I measured it as 1 1/2" by 1 7/8". There are also White (#16692), Yellow (#21791) and Blue (#21792) versions of this pin.

All pins come with a black rubber mouse ear pin back.  I do have the brass butterfly pin backs as well.  If you would prefer one of those, please message me to that effect.  If pins are not in great condition, I will list the defect in the Condition section.  I try my hardest to weed out fakes and scrappers.  If you receive a pin that you feel is not authentic, please message me immediately for a refund.  

If I have multiples of a pin, I do not guarantee that the pin you receive will be the pin in the photos.  If you wish to see photos of the exact pin you will receive, please message me.

I ship pins out the day following payment in a padded envelope.  I am happy to combine shipping for pins purchased on the same day.   Place all the pins you would like to purchase in your cart and then pay. 

If you are unhappy with your purchase for any reason, please message me immediately.  I will happily refund your money.  I would love to have you join my repeat customers!
