World War Two

I have a copy of a 1937 Mein Kampf written in German.
Attached are five photos
The first photo is the dust cover jacket which has Jubilaumsausgabe (at the top) and Gefamtauflage 3 millionen Expl. (in the bottom right corner)
The fifth photo is a hand written inscription in German.
I have not been able to find one like this anywhere after searching for many hours on the internet.
Would you please share any information about this particular copy?
Is it rare?
What the value is if sold to a private buyer and/or at auction?
What does the handwritten inscription mean in English?
Does the inscription have any historical significance and does it add or subtract from the value? 
Thank you for your consideration.
 
Sincerely,
Rick Clark
