Here are my current "Top 10."
Whelan painting from THE GUNSLINGER. My favorite painting from my favorite specialty press book.
Final galley proof of THE SHINING. My favorite King novel.
"Wimsey" manuscript. 15 typewritten pages of unpublished manuscript.
Letter written by King to Forrest Ackerman at age 14.
First state dust jacket for 'SALEM'S LOT.
Lettered (asbestos) FIRESTARTER.
Comics Review #3 with two chapters from "I Was a Teen-Age Graverobber." I got King to sign this in 1998.
Stephen Gervais' artwork for the dust jacket for Grant's edition of CHRISTINE.
Salt Hill #1 with King's poem "Dino." I think because this is relatively new and I had so much trouble finding one that this is a current favorite.
A couple of signed/inscribed copies of CARRIE from King's first "official" book signing.
