For sale : a pair of vintage ceramic bookends with green and brown glaze and an impressed pattern of mediterranean style medallions. They measure 4.25" x 5" x 6" tall.
The letters "AB" are inscribed into the clay on the back side of each bookend. I've not been able to determine if the bookends were made by a known company or an individual.
They are in excellent condition with no cracks, chips, or crazing.
