THREE TYPED LETTERS SIGNED (TLsS). Each 1 page, dated 21 July 1962, 23 April 1966 and 25 April 1966, all to "Reg" [Reginald Bretnor], each signed "Isaac." Three letters to SF writer and critic Reginald Bretnor (1911-1992), the first devoted to Ferdinand Feghoot, a popular intergalactic punster invented by Bretnor, many published under his pseudonym Grendel Briarton in THE MAGAZINE OF FANTASY AND SCIENCE FICTION. (For the uninitiated, Feghoots are short, short joke stories with the punch line a terrible pun.) Asimov sketches out an "idea" for a Feghoot, "without attempting to put it into literary form, so that you can do that part in your own inimitable fashion." Asimov's two other letters concern the reprint fee offered by Doubleday for a short story by Bretnor that Asimov selected for an anthology he is compiling. "As you guessed, Doubleday handled the matter, not I, but as I said in my previous letter, they meant no harm and there was much consternation in the Doubleday offices, partly because they are really a very nice, and very ethical publishing house - honest - and partly because they were afraid I would be upset - and so I was. Anyway, please let me know what you want done, in line with my suggestion in my previous letter (mailed yesterday afternoon)." Faint mailing folds, else fine. (#96328).
