Help authenticating Auschwitz I.G. Farben book

[ZeraAmalek]

Greetings, Yesterday I've stumbled upon a book used which ostensibly originates from a library in Auschwitz III Monowitz camp. There are stamps on the book bearing the name of the comapny I.G. Farben and one stamp in polish of what is today Dwory S.A., which aqcuired the factory complex after the war. Do you think it's the real deal?

Thanks in advance, Rud.

I've seen a few similar online elsewhere for crazy prices. The book itself was published in 1941 so it is old, but personally I wouldn't pay what is being asked for a book on roadbuilding.
