Estee Lauder Double Cameo Perfume Compact

Estee Lauder Double Cameo solid perfume compact, with no perfume, but very collectible.
I found a record at one time of this particular pattern being a Christmas 1979 issue item.
I cannot guarantee it as such.
The ladies in the cameo are very well detailed.
A very subtle light blue/grey and trimmed in white.
It is in very good plus condition with no damage.
It measures appx. 1 ½” diameter.
I believe it is made of a non-magnetic metal such as aliminum.
