The selection features distinctive types of architecture from resorts large and small, from the Victorian and art deco eras, to 1930s' modernism up to the present day. Among six special stamps is Blackpool pleasure beach.
Royal Mail said all of the attractions have been newly photographed to mark the "resurgence of interest in the British seaside" in the past two decades.

All ten stamps can be bought in a presentation pack for £10.05. The miniature sheet depicting four pier stamps is available for £3.80.
