Hitlers Original Signature on a big document?

[frankandfrank]

when i looked at the www.detlev-niemann.de i saw this document:
Adolf Hitler - Ink signature for 900 Euro
"Tintenunterschrift auf einer Berufungsurkunde im März 1944"
ink signature on a "Berufungsurkunde" March 1944"
Is this a original handwritting signature of Hitler at this time March 1944 to a woman ???? What do you think?
