This is a vintage retro Everedy brand Cake Taker, cake saver, keeper, domed locking cake cover and base. The bottom is marked The Everedy Co Made in USA Frederick, MD. The base is 13" wide and the dome is 5" tall without the handle. I do not have the clear glass cake plate that would be inside, but they are pretty interchangeable. I have a few listed separately that might fit. The cake taker is in excellent condition.
