My German is more of the Heinrich Schnibble variety, although Spike Jones might understand it.
This was no 'slap-it-together-real-fast-for-the-market' affair. For one thing, it was entered into the National Socialist Book register on 18 February, 1941, nine months after the Fall of France. It was a very official/official publication, requiring official inspection and approval of both the military and the Party. One thing the Nazis were really good at was setting up a parallel bureaucracy. It was almost as if the Reichsministry of Paper-clip Supply had a parallel in the National-Socialist Office or Paper-clip Supply, a division of the National-Socialist Department of Strategic Paper-clip Co-ordination or something.
In the case of this book, it was checked and approved by the Army and the Party both. Title page translates roughly as:
The War in the West
The Fuhrer's Soldiers in the Field
Volume 2
....... and below that........
Issued by
Colonel of the General Staff
Hasso von Wedel
Section Chief in the High Command of the Armed Forces
and
National Office Leader
Heinrich Hansen
National Press Office of the NS German Workers' Party
The bottom line tells you the name of the printing/publishing company.
On another page there is a list of illustrations, including a separate list of COLOR photographs, very unusual at this time. Colour film processing was very tricky at that time and the film not available generally. Check the names of photographers of the Colour plates especially; Heinrich Hoffmann, Hitler's personal photographer, made a special trip to Dunkirk right after the Allied pull-out and shot rolls and rolls of colour. Some of these were published during the War, but Hoffmann hid most of the negatives for 20 years following the War and they were generally believed to have been lost. He brought them out, finally, in 1965 and they made quite a stir in the London papers' weekend magazines. You just might have some of his photos.
You remark on the quality of the paper. It is quite good enough that it even comes through in digital photos! That this was an OFFICIAL souvenir commemorative publication is beyond doubt.
As to dollar value, I have NO idea. All I know is that I really wish it were in my own small archive.
Hope this is some small help.
I'm off now to goose-step around the block a few times.
GREAT artifact!
