I'm afraid I can't find a picture on the Internet using Google image search. Maybe somebody can do better, as it's something I would have expected to find.
There's a well-known drawing of the court on page 138 of The Birth of the Titanic. It's also in other books.
The court extended over two decks and included a spectators' gallery placed above and behind the players. The official size of the court had not been finalised in 1912. Titanic's was 30' x 20', which was a bit smaller than the 32' x 21' recommended by the English squash organisation. At the time, the game was in a state of flux and there were many differences between countries and even between localities. Second class passenger Charles Williams called himself World Racquets Champion, but he was stretching it a bit, as there was no world body and no standard game.
