These seals were found with an advertising leaflet put out by W.R.F. Avery & Co. There are two types of seal, both with the Davenport Demon Series logo in the middle. One had ‘Sugared Almonds Samples’ around the edge, the other ‘Eau de Cologne The Mark of Quality’. We do not know if these seals were samples from Avery, or whether Davenports actually used them on joke products. Either way, it seems likely that Davenports purchased their seals from Avery.
The Avery leaflet is illustrated in View Details. Its purpose was to encourage customers to purchase seals commemorating the coronation of King Edward VIII, which was scheduled for 11 May 1937. Examples of such seals are shown on page 3 of the leaflet. In fact the King abdicated in December 1936, so there was no coronation for him.
