London 2012: Olympics and Jubilee Oyster cards unveiled

There are 250,000 cards to mark the Queen's Jubilee

The Queen and animated characters in front of Buckingham Palace feature on two commemorative Oyster cards.

The special pay-as-you-go cards, one for the Queen's Jubilee and the second for the London Olympics, will be available at Tube stations in Zone 1.

About 250,000 Jubilee cards, featuring an official portrait of the monarch, will be available from mid May.

There will be 1.5 million Olympic editions of the card for travellers from mid June.

The commemorative cards will cost £10, which includes a £5 deposit and £5 credit, Transport for London (TfL) said.

Up to 1.5 million cards for the London Olympics will be available from June

The Olympics Oyster card includes images of sports, the Diamond Jubilee Pageant on the River Thames and bunting to mark the summer of events in the city.

Last April TfL issued 750,000 special Oyster cards bearing a picture of the Duke and Duchess of Cambridge to mark the Royal Wedding.

Shashi Verma, TfL's Director of Customer Experience, said: "Transport will play a vital role in bringing people out to see The Queen during her Diamond Jubilee, and in getting people to all of the sporting and cultural events during the London 2012 Games and so it is fitting that we have limited edition Oyster cards that they can use and keep to mark these wonderful, once in a lifetime, occasions."
