Interesting archive consisting of four lengthy ALSs, totaling eighteen pages on eleven sheets, dated March-June 1972. All concern the writing and publishing of his autobiography The Moon’s a Balloon and a book with the working title You Should Have Been in Pictures. One letter, in part: “I hope my efforts will pay off and keep the trusty Balloon flying high…I will, in a desultory way, keep on hacking away at the novel…But I certainly will start up on ‘You should have seen me in pictures.’ However, Research…Putnam’s surely has a list of broke freelance writers on the west coast who can check the gossip columns of those days? (For instance I was involved in the Rex Harrison-Carole Landis scandal but even so I cannot remember what went on publicly.) I was making a movie with Mary Astor too, when that scandal and all those names suddenly blazed forth…but I badly need a refresher course. I want ‘Pictures NOT to be dreary gossip and nostalgia, I want it to be fun, gay, sad sometimes, but above all I want to make the reader wish he HAD been in pictures at that time—a time now gone forever.” The other letters discuss photographs to be published in the books, reviews, and work in progress. Also includes seven glossy 8 x 10 press photos showing Niven throughout the course of his life. In overall fine condition.
