Help with a First Class vestibule Photograph


I was watching the 1986 documentary "Secrets of the Titanic" and saw a photograph that seems to be a view to a First Class vestibule (I think the one on the port side on Boat Deck) from one of the First Class staircases. I've never saw that picture before and I would like to know if someone can tell me if it was taken in any of the Olympic-class steamers and if yes was it taken on Olympic?

Here is the picture:
