London's famous Underground subway system is celebrating its 150th anniversary this year, with the latest initiative being an exhibition that focuses on the subway's long and graphically rich history. For more than a hundred years, London Transport has commissioned posters from top designers and artists. Enlightened enough but more surprising is that copies of each poster have been meticulously archived, to the point where there now thousands of them stashed away for safe-keeping, while also being available for browsing online.
Poster Art 150 – London Underground’s Greatest Designs, will feature 150 posters from the collection, running at the London Transport Museum until October 27, 2013. But if you can't make it you can still browse the 150 posters online and vote for your favorite, which may prove difficult, given the number of gems from the twenties and thirties. If you find one you really like, the good news is that you can purchase a reproduction in the London Transport Museum Shop online.
