Arabia pottery is uber collectble right now: here we have Kosmos, designed by Gunvor Olin-Gronquist [or GOG, as noted on the backstamp.] Kosmos dinner service sets were made between 1962 and 1976; these are espresso cups, for that perfect morning cuppa.
Also featuring in the image- Kathie Winkle for Broadhurst pottery- a ‘Calypso’ platter. This was made in 1963; Kathie Winkle was so prolific in producing different designs [over one hundred] in the 60s that each design was made for less than a year. The transfer stencil outline has been hand-painted, and then over-glazed, so no two pieces are exactly the same.
The Arabia cups are for sale: $AU55/pair, as is the Kathie Winkle platter: $AU35. A fabulous ode to the 60s!
