This image shows a Steuben design glass bowl that was available for sale in the Corning Glass Museum gift shop.
The description states:
STEUBEN RETAIL SHOP
Corning Glass Center, Corning, New York
Open Tuesday through Sunday
Swirl Bowl. A contemporary centerpiece of world-renowned Steuben crystal, hand fashioned in the Steuben factory at Corning Glass Center.
–Close examination of the image shows that the curving ‘legs’ of the piece are only decorative, and the bowl is supported by a central glass column instead.
This image likely dates from the 1950s.
