I bought this Monart bowl on "Saleroom. com" thinking it was shape IG. It was described (correctly) as a Monart bowl with folded rim. When it arrived, it was as discribed "Monart bowl with folded rim", but a Monart shape that is not in the Monart catalogue. The diameter is 25cm and 6cm tall, the foot is a shaped one. The base is indicative of the post war era (highly polished base and pontil).
