Guteto was a science fiction fanzine by Myrtle Douglas (Morojo).
Guteto was published in Los Angeles, California, U.S.A. and was distributed by the Fantasy Amateur Press Association. Guteto was a vehicle for Myrtle to advance the cause of Esperanto, the 'universal language', 'guteto' being the Esperanto word for 'droplet'.
The first issue of Guteto was published in June 1941, and continued up to Volume 4, number 7 in March 1958.
Along with Atres Artes, Black Flames, Chanticleer, Futuria Fantasia, Ichor, Le Zombie, Lethe, Nova, Shangri L'Affaires, and Voice of the Imagi-Nation, Guteto was included in the anthology fanzine Pacificon Combozine for the 1946 Pacificon Fourth World Science-Fiction Convention.
