Query: Is NOT the official autobiography!

Be VERY careful to be sure this is actually what you want: I bought it when Amazon recommended it in response to my search for the official autobiography. Since the seller did not have a disclaimer that it is not the official autobiography, I didn't know until it arrived and I was able to see the publish date that it was an unauthorized printing.For everyone searching for the full autobiography, which was printed WITH permission (this book and all others were printed previous to 2010 and thus unauthorized), you want the one edited by Smith, Griffin, Fischer, Frank, Goetz and Myrick. Volume 1 was released in November 2010. If your book is not volume 1 of a 3 volume set, it, like the above book, was printed in violation of Mark Twain's explicit instructions not to print his memoirs until 100 years after his death.
