Tolkien's The Silmarillion, True 1st
J. R. R. Tolkien
Boston: Houghton Mifflin, 1977.
The true first printing, as denoted by a misprint among the other books listed by the author, "Father Giles of Ham" instead of "Farmer."
Tolkien considered this his most important work, a great collection of tales and legends that set the stage for the Ring saga, with beautiful fold-out map of Beleriand.
A good copy, in unclipped jacket.
