High price for a signed knights cross winner photo!

[frankandfrank]

Hello,
i see the last auction from Andreas Thies, Germany. Look at
www.andreas-thies.de the last catalog!
There was sold a signature under a newspaper photo from
H.J. Marseille, diamonds winner of the luftwaffe and best luftwaffe ace (west) for 1500 Euros without tax.
A very high price for this item or what do you think?
Whats the price for a Marseille signature in USA or Australia!
regards
