These lovely small glass buttons were made in USA by Leo Popper & Sons in the late 1890’s or up until 1915. They are the only three that I have in my collection. They are always colourful and glitt ery in the Button books. They have a metal loop shank. The yellow one was a real find for me as I rummaged in a small dish of dirty old buttons in a junk shop and for $2 got it and a few old plastic buttons. I didn’t know at the time exactly what it was but knew it was glass. When I got out of the shop I couldn’t stop smiling.
