Studio pottery oval best baking dish (77)

This is an absolutely beautiful studio pottery oval baking dish, in excellent condition - no chips, scratches, or cracks. The sides are slightly best darker than the bottom, probably from being in the oven. This has a lovely blue glazing on the inside, with a white swirl pattern. The rim, outside, and bottom are rough, and the maker's mark on the bottom is a bird. This measures 11 and 1/8" long, 7 and 5/8" wide, and 2 and 1/4" deep. (77)
