Susan-- I don't think his authorship of that introduction has ever been questioned, but late in Twain's life a fellow by the name of Rev. Levi Powers of Haverhill, MA sent Twain a pile of books with questions written on the end papers for Twain to answer. The Reverend was cleverly seeking Twain's autographs in his Twain first editions, and his ploy worked. In my copy of Carolino's NEW GUIDE Powers wrote to Twain "This is certainly funny, but how did it ever manage to see print?" Twain wrote his answer below: "It is genuine. And good. Mark Twain." So, for to be one answer at your question posing it my say would have a Yes.
