According to Eve's book cellophane labels were used after the first few months of production. The first labels were red on paper followed by red on cellophane. Red or gold were first quality, black second quality. It also implies only items sent to retailers were labelled. It would appear that the multi-coloured boxes were used from the late 1970s onwards. The dishes appear in the 1971 catalogue (no 70 shown) and the server on a 1982 poster. Numbers seem to be 'chronological'.
