Kupfermann Print

Hello,

I purchased a print, and I would like to know more about it. Can anyone verify that this is work by Jacques Kupfermann, or how I could learn of the title and value. Thanks!

A close up of the signature would be good, I don't think it looks like his style though.

Interesting about the print; Jacques's signature varied quite a bit over time and perhaps even at the same time periods; sometimes cursive as this one is and sometimes printed in block letters.
I think this print could well be one of his.
