This is a new poster for Transport for London, drawn by Thibaud Herem as part of the 150 years of the London Underground birthday. TFL now have an official Tumblr that they will be filling with images for the anniversary. Talking of posters on the Underground, there is a great series running currently, drawn by French illustrator, McBess. They are general safety warnings with poetry written by members of the public and are all over the place in various sizes. I think we’re in a new golden age of design for the London Underground.
