The Truth About Harry Beck, a play about the designer of London’s iconic Tube map, is at the London Transport Museum’s Cubic Theatre through January. Writer and director Andy Burden spent years working on the play. So far reviews have been mostly positive: Theatre Vibe’s Lizzie Loveridge found it “charming,” Everything Theatre “warm,” and Broadway World calls it “as reassuring as a comfy pair of slippers,” whereas The Arts Desk’s take is more mixed and The Standard dismisses it as “chock-full of mugging, direct address and chuntering dimwittery.” BBC News coverage.

Not coincidentally, it’s the 50th anniversary of Beck’s death. London map dealer The Map House has an exhibition to mark the anniversary: Mapping the Tube: 1863-2023. They’re a map dealer so the displays are for sale, including a draft copy of the map and one of only five remaining first-edition Tube map posters. Runs from 25 October to 30 November, free admission.
