Berghof book stamp?

[nigelP]

Does anyone know of a stamp like that shown being used on Hitler / Berghof books? Is it likely to be fake? There are no other unusual markings and the 1936 books are in there usual hardback covers.

The only fact i know about the berghof library is that it was shipped to the states and is currently located in the white house.Unsure as to whether it was shipped in its entirety,be interesting to see if this is original. best of luck nigelp and thanks for showing

I've come across these stamps before and believe them to be correct. The US. government seized a lot of them I recall and a bunch hit the market many years back.
