First commemorative postage stamp (1924)
Great Britain’s first commemorative stamps were issued to mark the first day of the 12 month British Empire Exhibition at Wembley, which ran from April 1924 to 1925. Royal Mail had a pavilion at the Exhibition and visitors could post items from the site. This machine cancellation die for printing slogans on covers has the impression: 'BRITISH EMPIRE/ EXHIBITION/ MAY- 1925-OCT.'
