Large metal floral frog vintage

from my grandmother's estate Daisy manufacturing company 5 in diameter metal floral frog In 1916, William R. Struck of Dazey Manufacturing patented the first metal cage flower frog. It was designed to be camouflaged by the stems and leaves of a floral arrangement, letting the bouquet speak for itself. Frogs were produced in a wide variety of sizes; some included multiple tiers of cages that allowed for more complex displays. Stems were inserted into the different holes, which anchored them to the device and held them at the same level, giving them equal access to water. The metal cage flower frog could achieve these feats, all while remaining virtually unseen. Garden clubs quickly embraced the metal cages because they permitted more artfully arranged flowers than had been previously possible. Many had complained that vases and decorative frogs made the flowers stick up straight; the metal cage addressed this limitation by allowing flower stems to be inserted at various angles. Publications also promoted these devices over their decorative predecessors because the design of the cage enabled even the amateur floral artist to create dynamic arrangements quickly and easily. These cages were the dominant type of flower frogs used by both professional and amateur floral artists until 1954 when Oasis was invented.
