Gris, a master of disguised images, presents a table brimming with coffee cups, stemmed wineglasses, a bottle of red wine, a bottle of Bass extra stout ale with its distinctive red diamond logo, a newspaper, and a guitar. Yet this painting has another equally compelling identity: a bull’s head. The coffee cup at lower center doubles as the animal’s snout, a black-and-white concentric circle at left is a “bull’s eye,” the bottle of ale is an ear, and the sinuous edge of the guitar is a horn.
