Supramundane Stories is believed to be the first Science Fiction zine to appear in Canada, and perhaps the first zine to be published in Canada. The first issue was published by Frome in January 1937. The second issue appeared in March 1938. Only two issues were ever published, although Frome remained active in Science Fiction fandom clubs and circles. Nils Frome was also a contributor to the 1940's SF fanzine Canadian Fandom.
Contributors to Supramundane Stories included H.P. Lovecraft, Lionel Dilbeck, Rider Haggard and Clark Ashton Smith. H.P. Lovecraft contributed "Nyarlathotep" and "Notes on Writing Weird Fiction", both appearing in the second, and last, issue in 1938.
