I know what you’re thinking : "Sigh, once more does someone ask about Hitler signature, even if that can hardly be authentified online".
I’m aware of this problem but to amass nonetheless opinions of eagle-eyed veterans of collecting still appears relevant to me.

This postcard was recently found in a photo album in Germany, according to the seller. The signature seems to have faded as time flew, which could be a good sign of historicity. Uncertainty remains anyway.
Would you be so kind as to help me on that costly one ?
