The typed‑set Advance Uncorrected Galley Proof of Pet Sematary is one of the rarest pre‑publication states ever produced for a Stephen King novel. Created in an edition of only 50 copies, this proof predates the 1983 first edition and represents the earliest stage of the book’s production—assembled directly from the publisher’s typed manuscript setting before final typesetting, formatting, and editorial corrections. This proof is in fine condition.

Unlike later printed proofs or ARCs, this typed‑set galley reflects the raw, working state of the novel as it moved through the publisher’s editorial pipeline. It may include uncorrected text, spacing and layout anomalies, editorial marks, or pre‑publication formatting not present in any retail edition. These elements make it a distinct bibliographic artifact, offering a rare glimpse into the developmental history of one of King’s most iconic and unsettling works.

Because only 50 copies were produced—and all were intended strictly for internal publishing use—surviving examples are exceptionally scarce. Very few remain in private hands, and even fewer appear on the open market, making this one of the most desirable proof states for advanced Stephen King collectors.
