Tolkien was more than just an author.
JRR Tolkien, not just an author.
Some of the illustrations are simply stunning.
He knew how to draw/ink/paint trees that's for sure.
My first version of the Hobbit has/had (not sure where the book is) this cover.
Tolkien does some neat calligraphy/lettering too.
And maps - is there anything he can't do?!
And he even designed the book binding and dust jacket of the first edition!
So basically the man was a graphic designer too.
