Vintage, Art Deco L.E. Smith Greek Key Vase

Vintage, art deco, L.E Smith Glass Company Greek Key vase. This is a black amethyst colored vase, there is a small lip that runs around the top edge which allows for the potential of a flower frog to be added. This specific pattern was made from 1926-1937 (so we’re bordering on antique and not just vintage!), This stands 6 inches tall, there are no chips or cracks. There is two areas on what I would call the backside, that appear to be a small circle and other circular impressions in the glass. They are not deep or sharp which makes me feel that they are mold marks ask this is a pressed glass piece. They can be seen in the second to last photo, as well as a photo showing the amethyst coloring.
