1940s vintage art pottery, green glaze pitcher vase, Shearwater pottery from Mississippi

Vintage art pottery pitcher in a beautiful mottled green, marked Shearwater with the circular mark. We've been told this is probably 1940s.

It's about 5 1/4" tall overall, in very good condition without chips or cracks. I love the shape of this piece, great Craftsman style lines in a classic color!
