This image is of a large country house once owned by Georg Schilcher. I have been unable to identify it further.

There is no description on the back of this card, other than the publisher, which is shown as:
Eigent u. Verlag: Heinrich Uhlschmidt, Oberammergau
–Judging solely by the publisher’s tag, this may be located somewhere near Oberammergau in Bavaria.
This image likely dates from the 1920s.
