This London Underground Map (Diagram of Lines) from 1981, produced by the London Transport in England, is a wonderful piece of ephemera from a pre-internet world. Full of adverts from the time including Madame Tussaud's and the Wimbledon Lawn Tennis Museum, it is a wonderful snapshot of London tourism in the early 1980's.
The map measures approximately 30cm x 21cm. It has been stored folded but lies flat and bears few signs of age (see photos). Overall it is in good condition for 1981.
I have several maps (including geological maps) available so check out my other listings and save on postage. Thanks!
