The Lettered edition has a second, alternate version of Ray Bradbury's story, along with a hand written note telling the origin of the story. Richard Christian Matheson also provides three early drafts of his story with handwritten corrections. Matheson and Bradbury are signing only the Lettered edition, and Jerry Williamson signed both the Numbered and the Lettered before he passed away.
Masques V was a labor of love for Jerry Williamson, who died on December 8th, 2005. As his health began to fail him, he was overwhelmed by well-known authors who without hesitation submitted stories as a tribute to Jerry. In a note to those whose work will appear in Masques V co-editor Gary Braunbeck stated, "I think this will serve as a fine testament to Jerry's memory."
