Likely to attract particular attention are Andy Warhol's serigraph „Two Diane Keaton“ as well as a mirror object by Adolph Luther more than two meters in dimension. A painting by Philip Guston dating to 1957, and as such to the abstract period of this „New York School“ artist, offers a very fine example of the dramatic contrast between the vivid colours dominating the centre and the shades of grey in the background (€300,000–400,000).

Under the auspices of Viennese Modernism 
At the Modern Art auction on May 15th 2018, important international figures like Henri Matisse (Portrait de femme avec un collier € 280,000 – 320,000), Edgar Degas (€ 200,000 – 300,000), or Fernando Botero (€140,000–180,000), will share the limelight with artists who like no others represent the pioneering spirit of the fin de siècle avant-garde: Gustav Klimt and Egon Schiele. 

The auction's emphasis on Viennese Modernism also reflects the 100th anniversary of the deaths of Gustav Klimt, Otto Wagner, Koloman Moser, and Egon Schiele in the current jubilee year. 

Egon Schiele contributes a 1914 drawing, using both sides of one sheet, with a „Kneeling female nude“ on the facing side and a „Reclining female nude“ verso. Valued at 350,000 to 500,000 Euro the work comes from an Austrian private collection. Egon Schiele's estate awarded it to one of his relatives and it appears probable that the kneeling nude was coloured by his brother-in-law, Anton Peschka.
