This is a bookmark that I picked up in a place called Salts mill in Saltaire in Yorkshire. it is famous because it is where David Hockney the artist has a dedicated exhibition of his work in the old mill. I went years ago and can't remember much more than climbing the stairs and going through the door into what seemed to be like an art studio and then coming back out an hour later and climbing back in the car and heading back to wherever we were staying.
