From the Tube map to the famous roundel logo, the London Underground has generated some iconic design. We’ve looked before at some of the best London Underground poster designs, which often followed design trends of the day. Some of these romanticised a bucolic life in suburban ‘Metro-land’. But one set of designs is provoking astonishment online for a very different approach.

The ‘Underground for Climate’ campaign of the 1920s aimed to promote London’s subterranean transport system as providing a more agreeable temperature compared to option of travelling above ground. Today’s audiences are likely to view it through very different eyes amid the global climate crisis. And while one of the taglines might still technically ring true, it’s really not something to boast about.
