unknown artist (oil on canvas, 19th century)

[thr0n]

Hi,

I´m trying to find out something about an unknown artist - all I have
is the picture

http://freepage.escalix.com/_arts/thr0n/bild.jpg

and the information that it was painted by someone belonging to the
Leibl-circle.

Can anybody of you help me finding out something more (no commercial
interests, I´m asking just because I like the painting very much)?

Thanks in advance - all the best + kind regards from Munich/Germany
Jochen
