From the Usborne The World of the Future – Future Cities (1979).

The two futures paint a surprisingly accurate prediction of peak oil, bicycle transport, social decay.

This one gave me a laugh. Particularly the futuristic leisure suit. Also the idea of email. You have a physical paper document, feed it to the computer and it reproduces another physical paper document at the other end – more like a fax. It’s also funny how the futuristic teleconferencing still manages to make meetings seem really really boring.
