This large vase appears to have been made from the Tiffin Poppy Vase mold. It is 8-1/4 inches tall with a 3-1/2 inch top opening. The base is 3-7/8 inches wide.
Super Glass Co bought the old Cambridge factory and the right to use the Cambridge name on their production. How they ever obtained a Tiffin mold is not known.
The actual Tiffin Poppy vase this size has a small rolled top rim and the Tiffin Glass is thicker so the vase is heavier.
The Super Glass vase has also been found in rose. Sometimes it is found with a gold ormolu collar.
