From the Vespa Club of Melbourne archives.
I have collected these together to send to the new Vespa Club in Perth. There were once clubs throughout Australia under the banner of the Vespa Club of Australia.
The first three pictures document an epic ride from Perth to Sydney (via Melbourne) by three riders from the Vespa Club of Perth circa 1960. The pictures were taken in Melbourne. I have no details about who the riders were, but they were obviously sponsored by Mobil. The "Julie" in the picture is Julie Guererro, the Secretary of the Vespa Club of Melbourne. You can find more info about her here. http://www.vespaclubmelbourne.com.au/forum/topics/some-club-history-julie-Guerra
The three riders obviously scrubbed up for the photo shoot, which may have originally been publicity shots for Mobil. Note the oil cans strategically placed in the foreground of the first picture. The text on the side of the bikes reads: Perth to Sydney. Running on Mobilgas and Mobilmix II Oil". The woman rider's bike is nicknamed 'Junior'.
The final picture is just attributed as "West Australian Riders" and I have no more information. It was bundled with some pictures of a large interstate rally held in Adelaide, so I assume it is a photo of the West Australians arriving.
