Fifty-seven years ago, the Andrea Doria ocean liner was hit by the Stockholm ocean liner off of Nantucket. The Andrea Doria was returning to the US from Europe. The Andrea Doria sank during the late evening of July 24 and early morning of July 25, 1956.
Tomie had been on the Andrea Doria when it sailed to Europe. He wasn't on the return voyage because he stayed in Europe for a few weeks.
Here's a photo of Tomie on the Andrea Doria during the trip to Europe.
