Upon first glance, Jasper Johns masterwork Flag, 1994 appears monochromatic. As the viewer gets closer, red glows and white shimmers through the graphite worked over the canvas and the subtle variances of Johns’ precise painterly touch become even more profound. In this confluence of the familiar and the foreign, Johns forces his audience to reevaluate ‘things the mind already knows’. Join Edith Devaney, curator of the recent Jasper Johns Exhibition at the Royal Academy of Arts, in an exploration of the thrilling ambiguity that marks the very best examples of the artist’s output. Flag, 1994 will be offered as a highlight of Sotheby’s Contemporary Art Evening Auction. (14 November | New York)
