This photo was with Wally Munro's photo collection
There is no inscription on the back.
The vehicle is loaded up with sugar cane.
The man standing next to the driver side of the car looks like Wally Munro.
The man on the left definitely looks like the man leaning back against wagon wheel in one of Wally's bullock team photos.
Photo from Wally Munro Collection - May McGilvery (nee Munro).
