Spencer Collection
J. E. Spencer was a professor emeritus of Geography at the University of California, Los Angeles, and lived and worked in central China from 1932 to 1940. With his wife, Dr. Spencer purchased a total of 29 models of vessels that sailed the Yangtze River at the time, making it a precious snapshot of the existing types.
A book was published in the 1970s, at Texas A&M, and a paper on some of the vessels followed in the 1990s.
Below we present a quick snapshot of the models:
