A set of stamps and PHQ stamp cards was issued by the Post Office in 1983 on the subject of British fairs. They were designed by Andrew Restall.
The first three all show views of traditional fun fairs which tour the country during the summer months. Probably nowadays you don't get the menagerie shown top right though all the rides are there. We have one locally in August each year here on the green. It stays for a week so by the end the green is no longer green, but it recovers very quickly.
The 31p stamp is something of an odd one out because it shows one of the early produce fairs, still to be seen today in fairs such as the Nottingham Goose Fair. It is also noteworthy in that it is apparently the first British stamp to picture a cat.
This is a post for Sunday Stamps, now hosted by Violet Sky at "See it on a Postcard!"
See also a post I made just a couple of weeks ago showing the Festival of the Circus in Monaco. I bought the stamp and used it to send a card to someone long before I realised there was a matching postcard.
