This aluminium sculpture by the Sudanese artist Ibrahim El-Salahi is modelled after the Haraz tree, an acacia native to Sudan that appears frequently in the artist’s work. In the catalogue of his solo exhibition at the Tate Modern in 2013, the artist writes that the Haraz tree “through all, remains steadfast, silently watching over the passage of seasons and time”. During the fair, the artist will also present his first public work of art, a piece that expands on the theme of the Haraz tree. Last year, a portrait of a Sudanese man made the artist’s auction record, fetching €87,500 (€15,000-€20,000) at Ader auction house. Ibrahim El-Salahi, Meditation Tree (2018).
