A couple of images here that arrived in negative form only, so no date on them and no location. One thing they do have in common is both pictures include little monsters on wheels. The first image with the hand cart points to the vehicle being called 'Peter Peter Pumpkin Eater' and carries a deliriously boggle-eyed little freak. The second one shows three little scary tykes on trikes. Not what you want to see peddling down the street towards you... We reckon somewhere between the late 1940s and mid 1950s date wise, but can't be sure.
