London Transport Museum, in partnership with the Association of Illustrators, is now welcoming entries for the 2012 Serco Prize for Illustration.

This year's theme is Secret London and entrants are asked to create an illustration that explores a hidden side to the city.

Entries can depict little known or unusual aspects of the capital’s history, culture, characters and communities - past or present.

The competition is open to students and illustrators throughout the world. The top 50 entries selected by a panel of judges will be displayed in an exhibition at London Transport Museum that will open Tuesday 13 November and run until Monday 10 December 2012.

The winners will be announced at a private award ceremony on the evening of Monday 12 November 2012. The top prize is £2000 cash.
