We hear a lot (actually nearly everything) these days about digital, including digital Out of Home, posters as was.
But there have always been different ways to use the medium and in back in 1983 London agency FCO decided to demonstrate the sticking powers of Araldite glue by sticking a car to a poster on London’s busy Cromwell Road.
‘Elf and Safety’ would probably have something to say about this these days (the car was also supported by wires and stuff on instruction from the local council.)
The first special build poster? Maybe the best.
