Just a prop!
This is not the first IOTW that has featured this Blackpool photographer’s Minor ‘prop’. The eBay sourced photo shows either a family or group of friends seated in the shell of an OHC Minor Tourer while a second image in the archive shows the same Minor and backdrop with two teenage girls onboard. A third image, taken later, once again displays the same backdrop but in this one the Minor has been replaced with a 1935-37 Ford Model C 10hp tourer. (Thanks to Mike Costigan for this information) Clearly, street photography was a lucrative trade in Blackpool in that early post-war period.
