This is London 2012! The Olympic and Paralympic Games.

 Thank you so much Derek for this superb cover with 4 definitive stamps dedicated to the Olympic Games that will take place in London from 27 July to 12 August 2012 (between 29 August and 9 September for the Paralympic Games). To note that London will become the first city to officially host the modern Olympic Games three times, having previously done so in 1908 and in 1948.
