Makers Mark S IV Art Pottery Mug Artist Signed

This pottery mug has the Makers Mark S IV emblem on the front. It has a speckled brownish earthy green glaze. The bottom is the textured potter and is artist signed. I cannot make out the name but it obviously starts with a Z. The mug measures approximately 4 in tall 3 1/2 in base 3 in opening at top Great condition. No chips or cracks. Appears to have never been used.
