• A new exhibition celebrating the art of the Underground opens at the London Transport Museum in Covent Garden tomorrow. Poster Art 150 – London Underground’s Greatest Designs showcases 150 posters with examples taken from each decade over the past 100 years. Artists include the likes of Edward McKnight Kauffer, Paul Nash and Man Ray. The posters were selected from the museum’s archive of more than 3,300 by a panel of experts. Visitors to the exhibition will be able to vote on their favorite poster as well as online with the most popular poster to be revealed at the end of the exhibition. The last major exhibition of Underground posters – the first commission of which was in 1908 – was held in 1963 to celebrate the system’s centenary. The exhibition is based around six themes – ‘Finding your way’, ‘Brightest London’, ‘Capital culture’, ‘Away from it all’, ‘Keeps London going’ and, ‘Love your city’. Runs until 27th October. Admission fee applies. For more on the exhibition and surrounding events, see www.ltmuseum.co.uk.
