This is a picture from a magazine I got called Underglaze Decoration by Marc Bellaire. First published 1957, mines 1982. There are some good 1950's designs in it and I will post some more when I am able. His ceramics are quite interesting. I would add a link but I am grappling with technology at the moment.
The other picture is of a couple of pots, similar yet different . No age to them as I look closer , most probably they are from golo but I liked the starburst designs.
