Zünd-Up: ‘psycho-dynamic’ street and park system

Zünd-Up, The Great Vienna Auto Expander, 1969. Pencil and red ink on tracing paper, 300 × 490 mm. DMC 2157.2.

An element in this Viennese collective’s proposal to extend the city into a newly ‘psycho-dynamic’ street and park system, this ‘Cortina-Bob-Bahn’ would have ornamented the gardens of the Prater with a drive-yourself roller-coaster tower some 1500 metres high.
