Visitors flying into Heathrow airport will see a giant painting of British medal hope Jessica Ennis on the ground below them.
British Airways is behind the large scale art piece that has been installed along the Heathrow flight path and it aims to remind arriving athletes that London is making the most of its home advantage.
The image measures 75 metres by 53 metres and covers an area larger than 15 tennis courts and 193 London buses. It took two days to finish the painting and more than 600 litres of red, white and blue paint was involved.
Alongside the image are the worlds 'Welcome to our turf' and it will be on display until July 17th.
"Whether you're a Brit coming home, or an athlete arriving for the London 2012 Games, this celebratory message reminds us all of the power of the home crowd and how important it is to get behind Team GB and Paralympics GB," said British Airways sponsorship manager Luisa Fernandez.
Ennis appeared thrilled at the large tribute and added: "I hope it brings excitement to homecoming Brits and reminds international athletes that we're ready and prepared."
British Airways are involved in a number of events during the Olympic Games and will be sponsoring a special area within the Olympic Park that will allow visitors to watch all the sporting action on large screens.
Park Live will be able to accommodate up to 10,000 fans, including many staying at central London hotels. Organisers are hoping that it will develop into a key location for the Games and allow people to watch medal ceremonies, live action, interviews with competitors and provide spectators with a meeting and picnic place.
