Eric, thanks for the photograph. I can't get to my books now, but in "Exploring the Lusitania," the photos were on a double page spread...it included your posted photo with smaller images surrounding it. The image I'm interested in was of a postcard. It was in the upper right corner. I keep thinking pages 50 and 51, but this may not be correct.
There is a nice photo in "Majesty At Sea: the Four Stackers," which show the lounge before carpeting and most furniture were installed. I believe it is credited to the Scottish Record Office. If you (or anyone else)have this photo, please be kind and post it.
Thanks and best regards,
Robert
