The New York art dealer Fergus McCaffrey has helped introduce Gutai and Modern Japanese conceptual art to the international marketplace. Broader audiences may benefit from a global approach to looking at modern art’s history by having opportunities to learn about hitherto unknown artists, he said. “Some, like On Kawara, who were long the best-known representatives of a particular place or genre, now must make room for our recognition of other pioneering conceptualists like, say, the Japanese Jiro Takamatsu,” he added. The “new” art history, Mr. McCaffrey pointed out, reveals that for numerous familiar places and periods, certain well-known artists, styles or movements “were not the only game in town.”
