Southwark Underground Roundel
Amid all of the justified hoo-ha surrounding the recent opening of the Tate’s new Switch House gallery extension, this lovely detail caught my attention. Sadly not permanent, Michael Craig-Martin’s wonderfully dayglo interpretation of the London Underground roundel brought a burst of fizzy colour out of the gallery and into the world. (And we Brits could all do with a bit more fizzy colour right now.) Image by Fred Butler.
