Rex: Ship of Ships- beautiful, but costly. However worth the price, if it wont cause you financial strain.
Eight Wonderful Days, and Transatlantici also worthwhile Italia editions. Both should cost between $50 and $75 apiece, depending on the value of the dollar.
The MUST HAVE Normandie book is the French one- I'll post the title later- available through Amazon.fr. Equally worth having is the French language Le Paquebot France. Both books are beautiful, have great photo reproduction, and are in the $50 range.
Many of my photos are in the Streater books, but I'vew not seen the end result.
