Hi, I'm working on an article about "Imperial Tombs of China" a show opening this week at the Portland Art Museum. I'm looking to compile a list of significant U.S. shows of Chinese art and artifacts drawn from the mainland. Also, Robert Thorpe, a leading authority, e-mailed me a note saying the most significant display to ever leave the mainland occurred in London in the 1930s. Unfortunately, he is unreachable for follow-up questons before my deadline. Does anyone know any specifics about this exhibition, i.e. a name, curator, or circumstances? Finally, am wondering if anyone on this list might have some thoughts on the politics of these shows. Seems there's been quite a few the last few years, despite the chilly political climate. Thanks much, Randy Gragg The Oregonian Portland, Oregon. I'm on a tight deadline on this -- Tuesday noon. So any help will be much appreciated.
