Throughout his career, West engaged in collaborations with other artists, such as conceptual Artist Bernhard Cella, conceptual artist Douglas Gordon, musician Fred Jellinek, furniture maker Mathis Esterhazy, and the artist Tamuna Sirbiladze (West's widow). For another exhibition in 2012, West collaborated with fellow artist Anselm Reyle on a series of furniture sculptures.
West was represented by Gagosian Gallery, Galerie Meyer Kainer, Vienna, and Galerie Eva Presenhuber, Zürich, until his death in 2012. Previously, David Zwirner had represented West in the US until 2001. At Frieze Art Fair in 2011, West curated the Gagosian Gallery's booth. A portrait of West made by Rudolf Stingel sold for a price of more than $500,000. West's estate continues to be represented by Gagosian Gallery.
