From Time magazine in 1939, an article about one of the first science fiction conventions:

Sold at U. S. newsstands are about a dozen pulp magazines with such titles as Amazing Stories, Astounding Stones, Startling Stories, Strange Stories, Fantastic Adventures, Thrilling Wonder Stones, Unknown, Marvel Science Stories, Weird Tales. In the pulp trade they are known as “pseudo-scientifics” or “scientifiction.” This week in Manhattan this amazing group of publications produced an amazing show: a convention of their fans.
