Mark Twain's Portrayal of Jim

I believe that the second picture, the one of Jim and Huck wading throught he river with the raft, is the most faithful illustration of the text.  It is a lot more subtle and difficult to interpret than the other pictures, but I think it works the best because it seems to be the least exaggerated.  I contend that Mark Twain portrays Jim as more of a character, rather than a charicature.  Yes, Jim seems to be a bit of an exaggerated character, but he also seems quite real and extremely tangible.  He is not the stereotypical slave of the time; he is knowledgeable in a number of areas, and he is extraordinarily opinionated.  Jim is clearly his own, unique, living, breathing, human being.  I believe that Mark Twain fairly portrays Jim in a way that any human being deserves to be portrayed--as a human being.
