I have to admit that we're not hugely interested in royal collectibles. I have a weakness for items related to Edward VIII, due to their unique place in history, but we generally avoid more recent items, unless they're unusual. This is an example of the sort of piece which piques our interest.
After their marriage in 1981, Prince Charles and Princess Diana settled into married life and starting a family. Two years and one son later, in 1983, they fully embraced their official role with a pair of Royal Visits, the first to Australia and New Zealand, and the second to Canada. As was -and is still- common practice, official commemoratives were produced in various materials, including some made by Wedgwood.
Here in North America, the most common example which turns up is a Wedgewood Jasperware sweet dish or pin tray in light blue. It is decorated with a white laurel leaf border and a center decoration consisting of facing portraits of Charles and Diana (also surrounded by laurels) with a banner underneath which reads, "Royal Visit 1983".
(As they do not specify where the visit was being made, it is entirely possible that these were made to be sold during both the Canadian and Pacific trips. What is certain is that the double portrait was actually originally modeled for the Royal Wedding in 1981, and was reused for this item.)
This example is as above, save for one important detail: the body is solid Terracotta Jasper. I don't know whether these were made to be distributed to visiting dignitaries (by the Wedgwood trade representative, not the royals) or if they were a special order item to be sold by one of the shops in Canada specializing in English pottery, but I am certain that this is the first example I've seen in this color.
It is signed "Lord Wedgwood 1983" on the back. Piers, the current Baron Wedgwood, is employed by the company as a roving ambassador, promoting the Wedgwood brand throughout the world. It would not have been unusual for him to have been in attendance as a trade representative on an official trip like this. (It is my personal opinion that the presence of Lord Wedgwood's autograph adds no monetary value to a piece.)
The dish is 4.375" in diameter.
Condition: as new, no wear or damage.
Mark: impressed Wedgwood marks on the back.
