Laszlo Moholy-Nagy isn't just an anagram for Lazy Goon Holy Slam but the name of a Hungarian designer who Frank Pick commissioned to create a poster for the London Underground in 1937. Liz went to a show currently on at the Tate Modern (Albers and Moholy-Nagy: From the Bauhaus to the New World) and bought me back a postcard of the poster pictured below:
As well as the pneumatic doors Moholy-Nagy also created a poster promoting escalators on the Tube. London Transport must have been particularly proud of their new pneumatatic doors though and the poster explained how they worked "The doors which are edged with rubber are kept closed by air-engine arms one for each door. The arms engage in slots in the doors which open when the arms swing round. The doors are held open by the arms. The signal to start cannot be given while the doors are open".
I assume they still work the same way today, given the amount of grief some of you gave me for saying that I sometimes barge into the doors as they are about to close and hold them open so I can squeeze myself in.
Anyway if you're into Bauhaus, the exhibition is on until the 4th June and if you show a valid Oystercard you can get 30% off the adult ticket price and pay £4.90 rather than the standard price of £7.
