This is a very nice hardcover book that was the result of a Kickstarter project in 2018 to reprint the original Neptune Monograph plus other photos and information. The books has nice thick quality paper for the pages. 

From the original Kickstarter campaign:

Imagine if you could read the same secret intelligence-report that the allied commanders Dwight D Eisenhower, Omar Bradley, and Bernard Montgomery used to plan D-Day. 

Soon you can.

We are bringing to life the original Neptune Monograph, a top-secret intelligence report from World War 2 that only exists in a few copies today. It has never been published and almost disappeared from history after the war, but we are now restoring the pages of one of the most important documents of WW2. 

The original 112 pages contained thorough information about everything from tidal forces to typical battle tactics and had the absolute highest security stamp during WW2: Top Secret Bigot - above Top Secret.

It described the German defenses and typical strongpoints, the risk of chemical attacks and was so thorough it even had an analysis of the soil type on Utah and Omaha Beach. The book will contain a one-to-one copy of the original Monograph, new historical context and rare photos to explore. 

in total app 250 pages in hardcover including the original Monograph, added historical context and rare photos We will restore every single page from 1944 to its original look as it was presented in the Neptune Monograph. The original Monograph will run on the right page throughout the book. Here you get a rare insight into the depth of the incredible intelligence work and literally cast your eyes on the same pages, that the allied command got in their hand for the first time six weeks before D-Day. Originally the left pages were blank. Here commanders could add their notes and latest updates. We have decided to use this space to give a deeper understanding of the Monograph and add historical context and rare photos on the left pages of the book to explore and get the full picture of how the information was collected. The Neptune Monograph was split into nine sections giving a deep and rare insight into the situation in Normandy six weeks before D-Day. All nine chapters will be in the book.  The Monograph has more than 14 pages of charts, maps, and graphics showing predicted German troop movements, tidal charts, and graphics of the layout of typical German strongpoints in Normandy as well as charts of the naval threat from warships and mines. The maps, charts, and folios will be restored and be in the book in full color.
