David Whittle works with South Eastern Railways With the dawn of Oyster card travel on London's over ground network, illustrator David Whittle has been busy working on a big advertising campaign for South Eastern trains. His wonderful artwork will grace key poster sites at railway stations across the network. The artwork is also used in direct mail, press, on buses, underground sites, and online, with his quirky characters being used for an animation on the South Eastern Railway home page.
