Here we have the R [rice] T [Tea] and C [coffee] containers- made from the new-fangled rigid plastic moulding process in the 60s by Nally. A new innovation, rigid moulding went on to replace bakelite in the production of kitchen canisters. This would have been originally a set of 5: the F [flour] and S [sugar] having gone AWOL.
Whatever, kitchen canisters are still highly collectible. I like to think the RTC set stands for Real Time Capacity. Or Regional Transport Commission. It’s up to you what you store in the R, T, C canisters. Roses, Tiramisu, Candy. Just some suggestions.
This set of 3 canisters is for sale: $AUD45
