The Two Towers would later be published on November 11 and The Return of the King was released the following year on October 20, 1955.
To mark the occasion, Harper Collins has released two new editions of the classic in the UK. The first is a boxed set featuring Tolkien's original jacket designs and includes an updated version of The Lord of the Rings: A Reader's Companion by Wayne G. Hammond and Christina Scull.
The second is a one-volume edition in a transparent slipcase featuring all 50 of Alan Lee's painting from The Lord of the Rings.
I hope they make it to the USA sometime soon! :-)
