Image is believed to be in the public domain.
Uploader comment: This appears to be two children, with a cat or a small dog at their feet and a taller person, with their head tilted, behind them. They are stood in a corner of my lounge which was originally the kitchen of the house, aside of where the range would have been and in front of a sealed up doorway that once led into the hallway. The house was built in 1953, and an unusually large amount of metal was used in it's construction. This photo was derived from one frame of a video taken with a basic security camera. Admittedly, the brightness and contrast of the image had to be changed to make any sense of the subject, but it is just one of a large number of such images I have showing various persons.
