The little stamps on the base of these dishes seem suitable for Ilja’s challenge of “stamp or imprint” today.  Moorcroft pottery is one of the most renowned in the world and famous for its colourful pieces.  I have some which belonged to a friend and noticed that two of them have stamps indicating that they have Royal Warrants.  Trying to date them it appears that the large dish with poppies reads “Potter to HM the Queen” meaning Mary, the wife of King George V.  That label was used between 1928 and 1936 when the king died and it was then updated to “Potter to H.M. the Queen Mary.”  The smaller dish with a hibiscus says “Potters to the late Queen Mary” who had been a keen collector of Moorcraft and later models continued to use her Royal Warrant until after she died in 1953, which dates the small dish to sometime possibly in the mid 1950s.
