Studio Art Pottery Oversized Mug Shape Planter/ Vase Stamped

Studio Art pottery vase or planter in a pretty green. Shaped like a wonky coffee mug and possibly is an oversized one. Nothing to indicate it is a usable mug though. Is stamped with the makers mark. Very good condition No cracks or chips. Possibly used for decoration only as it is very clean and looks unused. Measures 5.5" W, 4"H and 5.5" from front to handle. Holly branches not included.
