My mother had several unpainted ceramic pieces, including several Christmas and holiday pieces.  This one of a pair of singing nuns measures 9" tall by 6" across.  Mom etched her name, and in this case, "San Diego 1982" on the bottom.  Perfect condition with no cracks or chips.  You can use acrylic paint labeled "multi-surface" designed for items like plastic, metal, ceramics, etc., available at arts and crafts stores.  Regular acrylic paint will not stick.  Please search my user name for additional ceramics and other items for sale, and please e-mail if you have any questions.
