So far there have been 11 characters - you can see the Carnival Queen and Chelsea Pensioner below, followed by the Doorman, the Policeman, the Busker, the Beefeater, the Taxi Driver and the Flower Seller. I was asked to write the word Welcome in a style to reflect all their different personalities. These posters can be seen along the Terminal 4 Travelator at Heathrow. So if you're flying into Heathrow this Summer look out for this eye catching series of cheery Londoners!
