Lot Essay
Silvia Koller was the daughter of Broncia and Hugo Koller, who in 1918 joined Schiele's growing circle of patrons. Mr. Koller was an industrialist with a scholarly bent, and he features in one of Schiele's great portraits of 1918 (Kallir, no. P320; coll. sterreichische Galerie, Vienna). His wife Broncia, ne Pinell, was a painter, as was their daughter Silvia. Schiele also drew Silvia's brother Rupert (Kallir, no. D2475). Schiele was a frequent visitor to the Kollers' summer home in Oberwaltersdorf; hence the initials "O.W." at lower right in the present work.
