Signed in this paper is read completely elementary and unambiguously; strange that you asked it for attribution. You have no pattern, and etching (perhaps as metstsotinto, the photo was hard to see) the famous German graphic artist Ian George (Georg Jahn, 1869 - 1940). About him enough detail written on the website:
http://freenet-homepage.de/georg-jahn-1869/. There is also an extensive article in Vikpedii:
http://de.wikipedia.org/wiki/Georg_Jahn.
Prices for his work - here:

But this - the prices in the West and in Russia you can easily divide them into 3 or even 5.
