Here is a Bisque Porcelain Vase marked with only the letter "F" on the base. I believe this vase was made in Austria around the 1920's-1930's by Mathilde Flogl. This hand painted vase measures 6.25" tall and is 2.5" wide across the base. The overall condition is excellent with NO chips or cracks. A lovely bisque porcelain vase to add to your collection.
