From Centipede Press’s newsletter:
This title, limited to just 200 signed and numbered copies, is selling very very quickly. It also has a list price of $100 but is currently on sale for $35 off. That sale will end in a few days. With the original novel, the long-forgotten prologue, extra stories and the first chapters of an unpublished book, loaded with illustrations, an interview, and other good stuff, this is the definitive edition of this classic novel. You can order it here:
