Something elaborate - rococo? - about this, with some mystery about what is on the other side of that window.

An interesting observation, Bob. I was mainly interested in the rectilinear background behind the elaborate curves of the iron, but that style of blind is associated (for example, in film noir) with the concealment of evil. So I understand this better now, since that may well have been in the back of my mind.. Thanks.

Remarkable mix of lines, and as you say, half mysterious...

Thankws, José.

Interesting contrasts in shapes and shadows.

Thanks, George.
