Camberley Kate
Camberley Kate was famous around the Camberley, Surrey, area (near to where I grew up and where I lived for a few years) for taking in stray dogs and promenading around the town with them en masse. Most of them walked, others, perhaps the favoured ones, were pushed around by Kate in her, presumably custom built, trolley.
I'm not sure what is going on the left-hand side of the picture, the dogs in the carriage seem to have merged and morphed into some sort of cyclopean, hairy hound-like horror. I don't think one can leave massed dogs unattended for long beofre this happens. Observe the Greek Dog cerberus.
This picture appeared in November 1972. Kate Ward, her true name, was 72 when the picture was taken. Another mention of Camberley Kate appeared on b3ta here and another picture can be found here.
