Rare, and an unusual item to have come from Premier. This is the only recorded example.
There is another leaf dish at Early Series 336. Other shapes in the range 336-341 also feature three-dimensional modelling, and immediately following that range shape-numbering enters a big gap. Clearly something out of the ordinary was happening at the time, presumably involving John Castle-Harris who did the modelling. For this particular dish, judging by the style of grapes, it has been suggested that perhaps Una Deerbon was responsible. Una Deerbon was a studio potter known to have frequented Premier Pottery, and who introduced Castle-Harris to Premier. Castle-Harris was her nephew.
