Notes: Apr. 1952←Jun. 1952→Aug. 1952 Vol. 13, No. 4. "Famous Fantastic Mysteries Combined with Fantastic Novels Magazine" at the top of the table of contents - "Famous Fantastic Mysteries" on the cover and spine. The editor is not listed but Gnaedinger signs the lead-in to the letters column. Bok, Lawrence, and Finlay are credited as the interior artists on the table of contents. The illustration on page 57 is not signed and actually looks like the work of Lawrence even though Finlay's signed work also illustrates the same story. Lawrence is presumed to be responsible for the other unsigned work with the exception of the illustration credited to Bok; it is the only one that is in his style.
