By Federal Glass this pattern known as Diana was manufactured in 1937 to 1941. The design offers distinctive swirling ribs and angular handles. An uncommon feature is the swirling ribbed pattern is mirrored within the base or bottoms of the pieces. The pattern was manufactured in crystal clear, pink, and this yellowish amber.
In Excellent Condition, the open two handled sugar is free of nicks or chips and the glass is clear. There is some roughness to the mold lines that is typical of depression era glassware.
The oval shaped sugar is 6" across from the outer edge of each handle and 3 3/4" across.
