This Vinegar Cruet is not marked but was made by Hull pottery in the 1920's. It was part of a large canister and spice set. It is a square ceramic jar with lid. The front is marked VINEGAR and has two blue birds. The cruet measures 2 1/2" on a side and 9 1/2" tall including the lid. This cruet is in very good condition. It is most unusual to find a cruet with the lid. There is crazing. These are expected on the ceramic canisters of this era. I have a large collection of Bluebird pottery listed in my shop.
