Puzzle Picture ~ Pictiwr Pôs

The Webmaster thought that this image recently retrieved from a dusty attic might be an interesting puzzle picture

Do you agree?

What is the subject of the picture? Where was/is it? When was it originally made? When was the photo taken?
(Two members of the Society's Committee were able to identify it!)

The answers will be published on this website in due course...
