Says that F. V. Luerzer is
"Frederick Von Luerzer" a German born artist lived 1858-1917

While

( http://www.hampshireantiques.com/new/painting/moose.htm )
Says that F. V. Luerzer is
"Feodor Von Luerzer" an Austrian born artist who lived 1851-1913

Obviously someone has their facts wrong!
So who is he?
Both websites attribute the same signature to a different person.

The painting "above" was signed by F.V. Luerzer and dated 1913
