The Science Fiction Hall of Fame, Volume Two is an anthology edited by Ben Bova (1932–2020) and first published in the U.S. by Doubleday in 1973 in two volumes titled “Two A” and “Two B”. In 1975, British publisher Sphere Books issued ten of the twenty-two novellas in a series of three paperbacks.
The illustrations by Eddie Jones wrap around to the back cover. All-caps Zipper is paired with Bullion. Both faces were released in 1970. While Bob Newman’s Zipper is a Letraset original, Bullion was drawn by Tony Geddes for Face Photosetting. The shaded style, Bullion Shadow, was eventually also produced by Letraset and consequently saw a lot of use, but the Solid style seen here was exclusive to the phototype provider from London.
