Greetings. I came across this photograph and wondered if it was taken aboard the Olympic. I deducted the style is of the Art Deco (1930's) era. Can anyone confirm this, and if not, which liner is this from?
The new cabins were much more spacious than the old ones, and decorated in a variety of styles, including this one which is Art Deco, but period reference call it "Moderne".
The cabin is probably A17 (WS re-lettered the decks) and is a composite of the old B25-27 cabins, plus the promenade deck adjacent.
That being said, your ID of A16 is probably correct based on these facts: (1) your source identifies it as "modern", (2) your source is probably later than mine, based on the drafting style.
I suggest my earlier drawing is based on an "As planned" configuration and yours is an "As built".
