This gorgeous set of Concentric Rings shakers was produced by Hazel Atlas. The catalog number for these shakers was 3530 and they were sold by F.W. Woolworth’s at least from 1939. The shakers stand 3 3/4” tall. They are in excellent condition with no chips, cracks, scratches, or flea bites. The glass is exceptionally bright and clear. The lids show a patina of age, but they go on and off smoothly. The shakers are marked with the Hazel Atlas logo.
