The official mascots for the 2012 Summer Olympic and Paralympic Games were unveiled on 19 May 2010; this marks the second time (after Vancouver) that both Olympic and Paralympic mascots were unveiled at the same time. Wenlock and Mandeville are animations depicting two drops of steel from a steelworks in Bolton. They are named Wenlock, after the Shropshire town of Much Wenlock, which held a forerunner of the current Olympic Games, and Mandeville, after Stoke Mandeville, a village in Buckinghamshire where a forerunner to the Paralympic Games were first held.
The writer Michael Morpurgo wrote the story concept to the mascots, and an animation was produced;it is intended that this will form part of an ongoing series concerning the mascots in the run-up to the Games in 2012. Two stories have been created about the mascots: Out Of A Rainbow, the story of how Wenlock and Mandeville came to be, and Adventures On A Rainbow, which features the children from Out Of A Rainbow meeting the mascots and trying out many different Olympic and Paralympic sports.
