Lloyd Arthur Eshbach was an American science fiction fan, publisher and writer, secular and religious publisher, and minister.

Marvel Tales and Unusual Stories were two related American semi-professional science fiction magazines published in 1934 and 1935 by William L. Crawford. Crawford was a science fiction fan who believed that the pulp magazines of the time were too limited in what they would publish. In 1933, he distributed a flyer announcing Unusual Stories, and declaring that no taboos would prevent him from publishing worthwhile fiction. The flyer included a page from P. Schuyler Miller's "The Titan", which Miller had been unable to sell to the professional magazines because of its sexual content. A partial issue of Unusual Stories was distributed in early 1934, but Crawford then launched a new title, Marvel Tales, in May 1934. A total of five issues of Marvel Tales and three of Unusual Stories appeared over the next two years.
