Untitled Jim Henson biography

An August 16, 1993 article by David Owen for The New Yorker mentions that a biography of Jim Henson was being written by Pulitzer Prize winner Ron Powers, to be released the following year. The biography was written, but the book was never published. 
According to a 1994 New York Times article:
Apparently, nothing came of Powers' attempt to find another publisher, and the book was never published. Since then, Powers has written two biographies of Mark Twain, and a third book about two young people who murdered an old man in Hannibal, Missouri, Powers' hometown.
