You can tell that it is the Olympic by the painting above the fireplace.
The Olympic painting shows the entrance to New York harbor and the Titanic's showed the entrance to Plymouth Harbor with a Warship in the foreground I believe.
The only copy I have of the Plymouth harbor painting is in the Titanic Voices book. The painting pictured there is a recreation by the son of the original artist which I can't post because of Copyright.
Picture is definitely genuine just labeled wrong.
Here are two pictures I have of Captain Smith for refernce. One image is a post sinking card I got from the Gurnsey's Titanic Auction and one was in a Diary I have from the 1890's written aboard the RMS Majestic. Not sure where the writer got it but it is period.
