Hungarian occupation stamp

[pdv006]

Here is something I found odd. This hungarian occupation stamp has BAUMGARTEN on the back side. Any info will be great.

That is the expertizing mark of Josef Baumgarten, who specialized in Ukraine, Western Ukraine, and Hungary. In this case, the mark is no guarantee that the stamp is genuine, as the expertizing stamp fell into the hands of a forger.
