Nostalgic photographs that capture unexpected moments of intimacy and humor on the UndergroundThink of the London Underground and what comes to mind? Shuffling human traffic, trains whirring through tunnels, tired silent faces. Mike Goldwater's pictures taken in the '70s and '80s, capture the moments of tenderness and life that lie beneath that: the kisses goodbye, the man cradling a cat, another smoking deep in thought, the homeless man curled up next to his belongings. We also see old ticket booths (before Travelcards existed), retro carriages, whisky adverts and bell flares. These images, full of human interaction, take us back to a time when it was fine to talk (and smoke) on our beloved Underground.
