In the confluence of the run of Desolation of Smaug and the winter gift giving holiday season, Author/Artist Otis Frampton has created more than a dozen Hobbit themed pieces suitable for Facebook profile covers, and is giving them away to the entire internet. All he asks is that you give him credit for the image in the picture description. Personally, though it draws on the movie depiction, I like his Gollum much better. Frampton is perhaps best known as one of the artists for How It Should Have Ended.
