Hi Sue,
Thanks so much for the info - it’s something that’s intrigued me for years. I won it in a raffle in 1991, when it was new, but I was only 11, so wasn’t bothered about the box or any information that might have come with it!
I always assumed the 284 referred to how many had previously been made, but if only 100 of the blue version was produced, maybe not. It is interesting that it’s a different colour, the pic doesn’t actually do it justice - it’s very bright turquoise in reality. One thought I have is that it could be a second - the rim looks a bit lopsided to me.
I shall have a look in to Helen Macdonald’s work - thanks again, it’s wonderful to see another piece like mine and get a name for it
