Vintage ''Order a Kahlua Duck Fart It's a Gas" Drinking Pinback Button

Vintage ''Order a Kahlua Duck Fart It's a Gast'' Black Pinback Button This includes the buttons in the photos. They show well and have normal wear from age and use. This is older, but not marked, so I am unsure of the age. The coin in the photos is in the photos to show the size and is not included. Roughly the size of a golf ball
