John Sladek wrote some of the best science fiction stories of the 20th-century and his parodies of famous s/f authors are uproariously "right-on". His talent went under-appreciated except by a few devoted followers, even though his satirical writing was on a par with the early Kurt Vonnegut.
Keep The Giraffe Burning is Sladek's second short story collection (of four published during his life-time) and contains seventeen stories originally published in (mostly) various SF magazines between 1968 and 1975.
