Huorns, from A Tolkien Bestiary
Just as those leaves are falling off the trees Ian Miller has found a beautiful original drawing from A Tolkien Bestiary - of those Huorns, perhaps even more special than the Ents. Somehow it had been overlooked until now but it's a rare find because the book is the definitive one on the subject and includes many of Ian's best-known images, all of which are now sold except this one. It's a beautiful and complex ink drawing, 14.5 by 9.5 inches. If you're interested just contact me.
Here you can see the actual drawing, and below that a detail.
