Man that looks weird. Fish eye lens?
Tipped the enlarger easel so the negative was projected onto the paper at an angle. Now the question is, Why?
Maybe a picture of a picture where the camera was at an angle to the first picture.
Another possibility is the photographer was using a view camera. A view camera has a lens board front and a film board/ground glass rear which are joined with a black paper bellows. The rear is often covered with a black cloth to make focusing on the ground glass easier.
A view camera has settings for modifying the image projected to lessen perspective effects. The front and back are normally parallel and aligned perpendicular to the central axis. They can be offset, tipped and turned to achieve desired effects. An example is standing close to the bottom of a tall building and shooting up at it will make it look like the Transamerica pyramid building. Tilting the film and lens boards can correct this and make the building look closer to what you expect to see.
A camera like this in the hands of an inept photographer can result in some bizarre effects. I suspect that this what we are seeing here.
Nice house. Folks that no doubt pretty well off. One of those 3 women to the left is probably the nanny, what with all those rug-rats running around!
Just imagine, no tv, maybe no radio, maybe no telephone, lots of books, no visible electric going to the house. Early to bed, early to rise, fresh air and sounds thru open windows.
That car has great camber for racing on clockwise tracks.
