How did a road authority appeal to the public at the 1969 Easter Show?- 25 April 2017

ATIPM member Graeme Pattison has passed on a historical video that the NSW Road Authority has found and placed on YouTube.
It is unedited film with no sound track of the DMR stand at the 1969 Royal Easter Show.
It was time when road construction had a fascination that it does not seem to have today.
