These seals, which were produced for the coronation in 1937, were apparently sold to allow people to advertise the forthcoming coronation and to generate their own 'illustrated' coronation mail. It is unknown when these were made available, but most examples are on covers dated the 10th May 1937, (the first day of issue of the first three low value definitive stamps bearing the portrait of King George VI).

          As well as their use on items of mail, these seals were also used on various other products connected with the coronation, (an example is shown below). It is uncertain at this time if the seals used on the various coronation products were available to the public for use on mail or if they were a special order produced for the manufacturer. To date no examples have been seen on mail that have been matched with commercial items, and any information on examples would be of great interest for inclusion in this work.
