A small, but important collection. Comprising 

[1] The autograph manuscript for The Frost Monstreme being around 12k words and 67 pages, single-sided on computer paper. All in Leiber's hand and written in pencil. 

[2] The autograph manuscript for Leiber's Rime Isle, being 250 pages of hand-written (in pencil) text, single-sided paper (the paper is from an old computer printout). Leiber's edits throughout. 

[3] Leiber's notes for [1] and [2], similar format: autograph, computer paper, pencil. Around 30 pages. Included is an explanatory letter (TLS) from Leiber to Stuart Schiff, who was publishing [1] and [2] under the Whispers Press. 

[4] Original draft typescript of The Curse of the Smalls and the Stars, a Fafhrd and Gray Mouser novelette, 59 pages with holograph corrections by Leiber. 

[5] Ribbon copy typescript for The Curse of the Smalls and the Stars, 75 pages edited for copy by Jessica Amanda Salmonson for Heroic Visions, with Schiff's edited intro (1pp) and a couple of letters between Schiff/Salmonson (and one to Leiber). [6] Carbon copy typescript for Adept's Gambit. 150pp, bound in a punched folder. Rectos only. Inscribed by Leiber to the second page. A few holograph amendments. Leiber first wrote this story in the 30's and it was read by the HPL circle, including HPL. It didn't get published until 1947 by Arkham at which point most/all Lovecraftian Mythos references had been removed. There are a few Lovecraftian references in the present copy, and it's longer than the published piece. This is almost certainly the second draft of the story (so not the particular one the HPL crew read). In an interview with Leiber, he notes that after HPL's passing in 1937 he revised Adept's Gambit and introduced Yog-Sothoth and Nyarlathotep. When he showed these amendments to his wife and Harry Fischer (co-creator) they both gave it a big fat nope and he revised it again for the 1947 publication. Given that the typescript has Leiber's California address on it (beneath the later Chicago address), there's a good chance he revised it in the early 1940s. All in all a superb set of manuscripts and a rare opportunity to own a group of manuscripts in the important Fafhrd and Gray Mouser series. [9565, Hyraxia Books].
