An intact passenger contract from the White Star Line for the R.M.S. Titanic, dated April 10, 1912.

Unfortunately this was a third class ticket, most likely equating to a watery grave.
Fortunately, this boarding pass was printed for service from Liverpool to New York, and though the ocean liner was originally scheduled to visit the city between the voyage from Belfast to Southampton, the Liverpool stop was cancelled at the last minute. This might explain the ticket appearing to remain unused.
