Musicians play in the C-Deck Second Class Entrance foyer of the Aft Second Class Staircase aboard the RMS Olympic.
The doors to the far left granted access to the Second Class Library, and the large slanted tube in the center of the room is the base of the mainmast. This photo was taken sometime in the 1920s, but this area on the Titanic would have looked identical. Click here to see this same area viewed from the deck above in a 3D model.
