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 a 19 year old Frome in January 1937 and contained fiction by Lionel Dilbeck and a poem by J. Harvey Haggard, and well as Frome's own writing. 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 later 1940's Canadian SF fanzines Canadian Fandom and Light.
Contributors to Supramundane Stories included H.P. Lovecraft, Lionel Dilbeck, Rider Haggard, Duame Rimel, and Clark Ashton Smith. H.P. Lovecraft contributed "Nyarlathotep" and "Notes on Writing Weird Fiction", both appearing in the second issue in 1938. In that issue also appears Clark Ashton Smith's poem Alienation. This was the last issue of Supramundane Stories.
