vintage plastic buttons art deco lilac & black, original cards, bag from Stampfer store Dubuque Iowa

Early plastic buttons on great art deco style cards, never used. Colors are lilac and black - one card of the lilac, two matching cards of the black buttons. Saved away for many, many years in a paper bag from Stampfer's - Dubuque! I've left them just as I found them, and will include the bag with the buttons.
