"Futuria Fantasia, Summer 1939" by Ray Bradbury is a science fiction fanzine created in 1938. At just eighteen years old, Bradbury launched this ambitious editorial project with support from the Los Angeles Science Fiction League. Though only four issues appeared before funding challenges ended publication, the fanzine attracted an impressive roster of contributors including Hannes Bok, Henry Kuttner, Damon Knight, and Robert A. Heinlein. Decades later, it received a Retro Hugo Award, cementing its place in science fiction history. (This is an automatically generated summary.)
