Gustavsberg Swedish round ovenware. I think it's rare, as there are fewer of these than the oval ones. I bought it about 15 years ago from a Scandinavian antique shop, but I've never used it. There are some slight stains that appear to be from oven use, but I think the condition is good for a vintage item. There may be some original paint and glaze unevenness, so please understand that it is hand-painted and handmade. I am also listing a smaller 20cm size.
