This sparking, antique glass cruet is Co-operative Flint Glass' pattern called "Twentieth Century" (20th Century) *aka "Ward's New Era". This is an impressive zippered diamond pattern introduced in 1900. This beautiful cruet measures 5 1/2 inches tall and is in outstanding condition, with just a few minor surface scratches consistent with age. The glass is clear, bright and really sparkles! The stopper is definitely newer, and not the original, though it fits well. This antique glass glows a soft yellow-green under uv light to further verify age. This is a fabulous example of Co-op Flint Glass for your collection! *The aka came about because Montgomery Ward sold it under the name New Era in their catalogs.
