ERG was a science fiction fanzine published by Terry Jeeves (1922- 2011).
Terry Jeeves was a major force in founding the British Science Fiction Association in 1958, and was responsible for naming the club zine, Vector, and created the art work for the first cover, as well as being one of the editors.
ERG was Terry's own personal fanzine and was produced on an old duplicator. ERG was always filled with Terry's illustration, which he handcut into the duplicator's wax stencils. The quality of the illustrations produced by others using the same medium was rarely matched.
ERG was published throughout the 1950s, and on into the 1980s.
