Yeah. Tolkien is obviously not underrated as a writer of English fictional prose and poetry and as a scholar and an essayist and an inventor of languages, but he was absolutely a master as an all-around aesthete, too. His maps and paintings and sketches and jacket designs are something special. Pair that with quality binding, and you have quite the physical prize. I have been slowly collecting quality hardcovers from the 60s-90s (the 30s-50s editions are more or less out of my reach), and they’re all very, very nice.
Too bad he never tried his hand at musical composition, really. Though there is a recording of him singing “The Stone Troll” to an old English folk tune; and the vocal line of “Namárië” from The Road Goes Ever On (song cycle by Donald Swann) is by all accounts more or less Tolkien’s own musical idea.
Oh, and this!
