Bush's Brain-How Karl Rove Made George W. Bush Presidential-James Moore-Signed This was bought at a estate sale. The previous owner was friends with Karl Rove and she told me that Mary B signed her book. She was friends with Mary B and she signed this book for her. The autograph is not authenticated. I can only find a couple of Mary's with the Bush family. Aunt Mary and Mary Bush. The lady that I bought this from had friends in the Bush administration is all I got out of her. Appears to be solid but you would have to get it authenticated.
