Not a streetscape, but a Bridgescape. The one taken from a northbound Austin A40 on the Sydney Harbour Bridge reminded me of VW's 1965 brochure of a similar view. I would put the earlier pic at late 1950s with a near-new Vauxhall Victor, and a surviving sit-up-and-beg Ford Prefect braving the crossing in the centre lane. In the VW pic, the Rover 75 must be at least 12 years old. The third pic was taken in North Sydney in 1967 and looks like a line-up of cars on the Bay to Birdwood run.
