Works from "Poems on the Underground" have arrived in Cambridge.
The initiative delighted millions of commuters, tourists and Londoners since the first posters appeared on the London Underground in 1986.
Now, the archive of this beloved literary project – which includes hundreds of posters, eclectic memorabilia and letters – has been donated to Cambridge University Library.
They include items from Nobel Prize winners Seamus Heaney and Louise Glück, former Poet Laureate Carol Ann Duffy, and Philip Larkin.
