12 Unusual Teal English 1940s VERY Deco Buttons - 2.2 & 1.8cm

12 vintage 1940s buttons - an unusual rich teal colour,
slightly domed, with a very deco design on the top.

In some lights it looks like a green teal, in other lights a blue teal
...a very clever button.
I have them in 2.2cm or 1.8cm in diameter and they
have a single integral shank at the back
