1957 World Scout Jubilee Jamboree Commemorative Stamps

"In early 1955, the Boy Scout Association sent a request for a stamp issue in connection with the Jamboree, and it was rejected in July 1955.

A second request was approved in spring 1956, and on 13 June 1956 it was announced in the House of Commons that three stamps would be issued.

Invitations were sent to nominated artists and printing firms to submit stamp designs, and 26 designs were received in October 1956. Royal approval was received for the final designs on 30 March 1957. The stamps were printed by Harrison & Sons, High Wycombe, Buckinghamshire, and they were put on sale from 1 August 1957."
