Olympic sport stamps

From David Macnamara by email:

Royal Mail is issuing a set of ten 1st Class stamps on 27 July 2011 to celebrate the one year countdown to the London 2012 Olympic and Paralympic Games. …

The stamps are the final set to be issued in its three year countdown which has seen a total of 30 stamps issued. The creation of 30 stamps marks the fact that this is the 30th Olympiad, and also represents every sport in both the Olympic and Paralympic Games. …
