Recording his city's rich architectural heritage has been a demoralizing task for Shanghainese photographer Deke Erh. While Art Deco buildings in Miami, New Zealand's Napier and even the Eritrean town of Asmara are lovingly tended, Shanghai has demolished scores of equally historic structures in its headlong rush for modernity. "I've been taking photographs of old Shanghai for 20 years, and I've continually seen these things torn down," says Erh. "But I still have hope. Even today, Shanghai has more Art Deco buildings than any other city in the world. If I didn't have hope, I'd have to give up."
