Publisher:Horwitz

Horwitz Publications was founded in 1920 in Sydney, Australia to produce Sporting Weekly newspaper. They expanded into paperback publishing with the Sporting Westerns series and Scientific Thrillers series and Australia's first science fiction magazine, Thrills Incorporated (1950-1952). in the 1950s, Horwitz moved out of comics and began producing paperbacks. Some of these appear to have been produced in association with Tandem in the UK.
