That's Fred and Andrew on the hood in a 1992 photograph by Marcus Bunyan (Australian, b. 1958).
Here they are back in the car in an image called Fred and Andrew Smoking a Joint in Paris (but only because of the artful cropping of the photo--they were in Australia, not France).
Apparently right-hand drive models of the Pontiac Parisienne were locally assembled in Australia until around 1969.
