Donatello was introduced by Roseville Pottery in 1916. Standard colors are green and white. Examples in gray are rare. Early Donatello pieces were unmarked, but a few have a raised Donatello mark or a blue ink stamp of the shape number and size. There were 91 shapes in the factory stock pages and an additional 18 in the July 1916 price list. Clean examples of Roseville Donatello with limited crazing are highly sought-after by collectors and bring premium prices.
