Fantastic studio pottery covered bowl or box by the master potter Warren Mackenzie. Simple and elegant covered round box form with striped brown and gray glaze, speckled here and there. Marked on the side of the piece with Mackenzie's "WM" mark, and probably signed on the bottom of piece as well but difficult to make out.
In good vintage condition, with no cracks or damage. The interior rim area has maybe 3-4 small fleabites, some are glazed over but at least one is post manufacturing - see last photo, near the logo, for example. They do not show when lid is on, in any case.
Measures about 4 3/4" tall, 5" wide.
