This week saw the mayor of London Boris Johnson unveil the eye-catching uniforms to be worn by the Team London Ambassadors during this summer's Olympics.
The 8,000-strong group of volunteers will be essential to the running of the Olympics, welcoming visitors to London and helping them make the most of their time in the city, promoting the vast range of events and activities taking place during the summer.
And those on London getaways should find spotting the Ambassadors thanks to their bright-purple shirts and trilby hats.
The mayor also unveiled the colourful 'pods' at more than 40 key locations across the capital where the Ambassadors will be based during the Games.
"With their purple shirts and quintessentially British trilby hats there can be no doubt that our Team London Ambassadors will be a highly visible presence during the Games," said Mayor Johnson.
"These volunteers have come on a fantastic journey since we launched the quest to recruit our volunteer army and I am really proud of the public-spirited people we have on board."
Aged between 14 and 85, and speaking over 40 languages from Albanian to Vietnamese, the volunteers come from across the London and were chosen following a rigorous selection process which saw more than 30,000 people apply.
Meanwhile, it has also been announced that a new exhibition is to open at London's City Hall which will give Londoners and visitors to the capital a chance to get a sense of what London will be like during the Games this summer.
The two-week exhibition will feature examples of the colourful dressing and bunting that will be on display throughout the city, plus a number of examples of how high streets and towns will be getting involved with the celebrations.
"With just over four months to go Londoners are starting to get a real taste of how London will look and feel during the Games, as well as how we will welcome the world during a summer like no other," said Mr Johnson.
