This is a rare piece from a range of blue and white (and also lime green and white) items made by (Australian) Fowlerware in the 30s.
I have a collection of the green (jugs, bowls, canisters, tea and coffee pots and so on) and the blue is surplus to my requirements.
It can be collected from My Mother's at Old Petrie Town sunday morning market or delivered within the Brisbane area by arrangement.
