3 Vintage Clear Glass Corn on the Cob Salt & butter Holders

3 Vintage Clear Glass Corn on the Cob Salt & butter Holders This is a lot of 3 vintage corn on the cob holders. They are all in good condition. I do not see any cracks or chips in them These belonged to my parents who were married in 1940. Not sure exactly when they are from. Each holder has a compartment for salt, butter and the corn. Each one is 10 1/2" long. They are a heavy clear glass.
