The First Impression of the first UK edition was published September 21, 1937 by George Allen &Unwin Ltd. It was limited to only 1500 copies. It exists out a light green cloth binding over boards, imprinted with a stylized Misty Mountains scene in deep blue ink along the top, all the way around, and a dragon at the bottom, both front and back. A dust jacket in green, black, dark blue, and white, showing a drawing of stylized mountains with the moon and eagles soaring above, a forest, and a river. The end paper maps in are in red, black, and white. All artwork is by Tolkien.
Originally Tolkien intended the flying dragon and the sun to be painted red, but budget restraints forced the red color to be substituted with black.

The very first printing had no color illustrations within the book itself, but included 10 black-and-white illustrations along with the the two maps (wich in the beginning were intented to have been 5 maps).
