Contributed by David Carrier / Born in Russia at the very start of this century, Ester Petukhova is a Pittsburgh resident. Her precocious new show includes seven small acrylic paintings, two of them with two parts, on shaped panels. Burgeoning Blue Screen shows a Russian at work on an old-fashioned computer. Indexed Landmarks 1 & 2 depicts a man, naked to the waist, holding a large fish. And Bread with Salt in the Wound presents a large loaf of bread, and is enhanced with glass beads. “It is a customary Slavic tradition,” the gallery label says, “to present bread with salt when welcoming a foreign nation or power.” Welcome, then, to the former Soviet Union.
