9 vintage buttons, 6 are 7/8", 3 are 1/2". French Military style.
Silver wings, silver star with rays on dark enamel. The color looks black, under very bright light it is very dark green.
I am told by the previous owner that the design originates with the French Military, Air Force. I do not know the actual age of the buttons.
Domed/rounded. The design is raised on the dark enamel.
Very attractive!
