2012 is, amongst other things, the 75th anniversary of The Hobbit. HarperCollins went a bit early, however, releasing The Art of the Hobbit last October. The book contains over 100 'lost' illustrations by J.R.R. Tolkien, including preliminary sketches, maps, plans and other charming scribbles. A wee gallery at the Guardian shows the changes in one particular image over time.
Cutest Smaug ever.
