British stamps have no name of the country – instead they have a silhouette of the Queen. This simplified mark started in 1966 and before then all the stamps had a little portrait of the Queen.
This set of stamps have beautiful composition and colours, by the same designer of Racket Sports of 1977, and you can see how difficult it is to combine modern graphics and the portrait with a State crown. It is interesting to read the discussions on this problem in the British Postal Museum & Archive, and see a few trial designs without the portrait, which were not issued.
