Card of 24 Vintage Glass Black/Red Flower Buttons Pre-WWII, 1/2" New Old Stock, #BK-406

Shiny, scooped glass, they may be handpainted and the black may actually be very dark blue. From Europe around the 1920's. New Old Stock, they've been in storage all that time; never circulated or used.  1/2" diameter or slightly larger, domed and plump, with a self shank. We are pretty sure this is the original card.  Limited supply; we only have one card of 24 buttons. The minor flaws the camera sees are barely noticeable in person in our opinion.
