Michael Stump "Maida Vale Station Roundel"
Maida Vale's glorious mosaic sign is an original design feature of this Grade II listed station. The Bakerloo stop celebrated its 100th birthday last year. When it opened, Maida Vale was entirely staffed by women — a novelty at the time, prompted by changes to the workforce during the first world war.
