“At the opening for the Drawing Center’s “All in One,” Tomi Ungerer’s first U.S. retrospective, swarms of visitors obscured the art on the walls. The crowd bent toward the artist, who was holding court and a glass of red wine, though none was being served. Ungerer, who is eighty-three, was in his element. For him, this retrospective is a kind of homecoming. After more than forty years in exile, his career is finding its rightful place in the New York art world.”
