I got the book from an internet site. "A swim for dear life". It was interesting, giving a little insight into Algernons life and what happened to his infamous fir coat, it was a bit sad hearing of its demise. The rest of the book was basically about the sinking of the ship, pretty much common knowledge but nontheless still interesting and was worth buying.
According to the book the car in the photograph was called "Dixie", thats either the name he gave it or its model name, its an american roadster and must have been quite famous locally. I don't suppose there were many of those being driven around the country lanes of East Yorkshire back then!
