Three books to a desert island

[RJNorton]

Although I realize I could take more, I think I would only take one. For some reason I am picturing this island as very small as well as remote. In other words there is not much to look at. To make up for this, I would want a book that has fascinating photos as well as fascinating text. So I would choose Twenty Days. I have had the book since the 1960s, and I never get tired to re-reading the text and looking at all the photos. It's the book that first really spiked my interest in Lincoln. If I changed my mind and took two, the second would be the book Gene mentioned - Lincoln, An Illustrated Biography (also has fascinating photos plus text).
