Lovely Hand Thrown Austrian Pottery Mug or Cup

This is a lovely little hand thrown, glazed, and painted pottery mug or cup handmade in Austria. It is marked with the maker, but I can't make it all out. This is a pretty light blue glaze with hand painted flowers or floral sprays on each side. It measures 3.75 inches high and 3.25 inches across the widest part. It is in very good clean condition, no chips, no cracks and no crazing. I do not know the glaze composition, so it is sold for decorative use. It is an auction piece. I do not know the age.
