Vintage 1982 Gustavo Madero Munozr Pan 82 Mexico Metal Tab Pin Pinback Button

Vintage 1982 Gustavo Madero Munozr Pan 82 Mexico Metal Tab Pin Pinback Button Does not appear to have been folded. Coin in the photo for size and not included. About the size of a quarter. 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 not included and shown to display the size. I have many similar buttons listed.
