I wonder if by "the Hobbit epic" they meant The Hobbit and LOTR combined?
As a kid I was utterly enthralled by The Mewlips, and the end of The Sea Bell still really moves me, but it doesn't surprise me to learn that it was rushed together. Although there was time for Pauline Baynes to do her usual marvellous work, so you'd have thought Tolkien would have a bit of time to work on his scansion?
Here's the Tolkien Gateway (grammar could have done with revision):
J.R.R. Tolkien's aunt
Jane Neave enjoyed the figure of
Tom Bombadil and asked him if he could make a book out of him that would make an affordable
Christmas present. Tolkien didn't feel that anything more could be told about Tom, but considered his earlier poem about him, that would be made into an illustrated booklet, thinking about
Pauline Baynes.
Rayner Unwin suggested to him to collect more poems with it so as to be a more publishable book, and Tolkien researched some older, half-forgotten poems the value of which he doubted but as he wrote to his aunt, he enjoyed rediscovering and rubbing them up and took a lot of work to re-write them.
Tolkien thought (and Baynes agreed) that the poems didn't fit together as a collection. Tolkien worked a lot to make them fit with each other and into
Hobbit-lore; he decided including a Foreword that would make this connection, and wrote
a second poem with Tom in order to fit him better into the world of
the Shire and Hobbits.
The Illustrations
Despite Baynes suggested that his poems were rather "felt", Tolkien insisted that his images were definite, clear and precise. He instructed Baynes that the illustrations "shouldn't be comical". Then she collaborated with art editor Ronald Eames, and finished six illustrations by August
1962. Though there were some criticism from Tolkien to Baynes' work, in the end, Tolkien credited for a large part Baynes for the commercial success of the book.
