10x7 inch (250x175mm)  black and white amateur photo of an unknown driver getting a push start in his Staride 500cc F3 car in the early/mid 1950s.
Sorry I don't know whatere the photo was taken, possibly Castle Combe.
 The Staride was an alternative to the ubiquitous Cooper F3 cars of the day which dominated for mule with drivers like Stirling Moss and Peter Collins.
