New York, Science-Fiction Plus, n.d. . Manuscript. Unbound. Typescript by Long for Hugo Gernsback and Sam Moskowitz's short-lived Science-Fiction Plus magazine, which ran for seven issues. This is from issue four. With annotations and corrections throughout by Moskowitz and Gernsback (mostly by Moskowitz in black pen and some pencil, some by Gernsback in pencil and red pencil crayon; there may be a third hand). An interesting set of emendments, particularly the removal of an entire paragraph toward the end. Given the indentations from the full-stops this is clearly a typed copy, possibly a top copy, and if so the only copy thus. There's a chance that it's a carbon rather than top, but the quality suggests not. 29pp. Near fine, with edge wear and a few creases to the corners. A typed piece of paper had been pasted over the original title on the typescript (the present copy was used for setting also). [8901, Hyraxia Books].
