Here are several old plastic buttons of various sizes, colours and periods. I keep them in a divided box just for interest sake. They are too good to throw out but not good enough to mount on a card. I do not know their age but guess they could be from the 1940s – 50s. Sometimes I just tip them onto a tray and “play” with them. They are quite tactile. The colours are not as gaudy as those of today.
