Hand-thrown stoneware pottery ceramic mug in ombre blue and speckled brown. The sturdy handle is wider at the top for thumb resting. 

It measures approx. 4.75" tall, 6" wide (incl. handle), and the opening is approx. 3.25" in diameter. It holds approx. 18 oz. Signed "Milly" on the bottom. There are letters impressed on one side of the mug (seen in pics). It's difficult to make out but I believe it's "HaF". 

I believe this is from the 1990s or early 2000s. It's in excellent pre-owned condition. May show minor/insignificant signs of use but no breaks, cracks, repairs, etc.
