In 1978 it was the 25th anniversary of the Queen's coronation and these were the cards and stamps issued by the Royal Mail to commemorate the event.
We are having a right royal time with commemorative events here. Next year we have the Diamond Jubilee, the 60th anniversary, of the Queen's accession to the throne and I imagine the following year will mark the same for the anniversary of the coronation. In between we have the 350th anniversary of the Crown Jewels, the House of Hanover in the Kings and Queens series, and of course the Olympic Games in the midst of it all.
I hope they do better than they did for the recent Royal wedding when the minimum you could buy was a sheet of four - 2 x first class and 2 x £1.10 - and the result is quite expensive. No cards at all!
