Dorotheum will offer Victor Vasarely's monumental painting Tomor, painted in 1974-75, at its Contemporary Art I sale in Vienna on Wednesday 18 November. The 190 by 190 centimetre acrylic on canvas carries an estimate of €180,000 to €280,000 and appears as lot 205 in the evening sale at the Palais Dorotheum. Viewing runs from 7 to 18 November.

The work has not been offered at auction for twenty years. Its provenance runs through Circle Fine Art Corporation in Chicago and then a private collection, and the canvas is signed, dated and titled on the reverse. For a painting of this scale, a two-decade absence from the saleroom is unusual, and the house is presenting it as one of the leading lots of its autumn Contemporary Week.

Tomor dates from Vasarely's mature period. Born in Pecs, Hungary, in 1906, he settled in Paris, where he developed the geometric visual language that made him the best-known figure of Op Art, and he worked there until his death in 1997. The large square canvas is built from the geometric rhythms and shifting patterns that defined his work, using precise colour and form to create a sense of movement on a flat surface.

The sale forms part of Dorotheum's Contemporary Week, which runs from 17 November to 3 December and offers around 550 modern and postwar works. Other highlights of the week include Ad Reinhardt's Abstract Painting (Green) from 1952, estimated at €400,000 to €600,000, alongside works by Egon Schiele, Giorgio de Chirico and Daniel Richter.
