Leviathan: "The World's Greatest Ship" Volume 4
USL: "LEVIATHAN: The World's Greatest Ship, Volume 4", by Frank Braynard, published in 1978, hardbound with original dust jacket, 436 pages.
Braynard has created what is probably the most extensive history ever written about a single ship. His ground-breaking series covers 6 volumes.
This book is volume 4 and picks up the LEVIATHAN saga in 1926 during the height of the ship's popularity and ends with the stock market crash in 1929. The ship's fortunes fell quickly after that. There are hundreds of great photos, including a section of color ones, which makes for wonderful browsing and reading.
Note: Even though Frank O. Braynard submitted his volumes to the Library of Congress and received back an LOC number, there isn't a Library of Congress Catalog Entry for any of the six volumes in this series.
