But now I'm really a bit shocked
It is this one:
http://www.gjenvick.com/WhiteStarLine/1909-04-16-Brochure-TheFamousBig4-NewYork-Liverpool.html
It provides a lot of information about and pictures of the Big 4 of the White Star Line, Celtic, Baltic, Cedric and Adriatic. I've listed the pictures by number when scrolling down the site so you know what picture I'm talking about:
*No. 3: We see people sitting in chairs of the same design as in Titanic's lounge; the sconce in the background is also almost the same which can be found there.
*No. 4: The most shocking one: We see the Baltic's smoking room, and on first glance it could also be Olympic or Titanic: The same stained glass windows, the same window framing, the same ceiling lamp and sconces between the windows... I can't say whether there are also the beautiful mother-of-pearl inlays due to the bad quality of the picture, but it could be. Only the ceiling design and the furniture are different.
*No. 5 & especially 7: The Writing room of the Adriatic remembers well of its counterpart on Titanic and Olympic: The large bay windows, the white wall and ceiling design, the lamps, the curtains and plants... Just stunning!
*No. 11: The bookcase clearly reminds of its counterpart in Titanic/Olympic's lounge
*No. 13 & 14: The cabin design is almost the same as the Harland & Wolff Type "B" on the Olympic class.
Of course there were a lot of new rooms and designs on board the Olympic class (as the Grand staircase, the dining and reception room, the veranda cafés...) But I was really surprised how similiar former ships' interiors were in comparision to the Olympic and Titanic.
