My darling Nita loved to sew. When she flew away to heaven she left her sewing machines and sewing stuff to me. She's been gone almost five years now. Only recently I finally went through all the sewing notions she left behind.
I found this fascinating card of detachable buttons! I've included the back side of the card because it has two remaining buttons, and thus you can see how they worked. I love these old things--so normally a part of people's lives, and now considered "vintage."
The buttons were made by the Tip-Top Products Company, in Omaha, Nebraska, USA. I'm not sure when they were made.
