Time Safari, Inc. 2055 Mug

First published in Collier's magazine in the June 28, 1952 issue, Ray Bradbury's sci-fi short 'A Sound of Thunder' is set in the year 2055 when time travel has become a practical reality. A company by the name of Time Safari, Inc. offers wealthy adventurers the chance to travel back in time to hunt extinct species of animals including dinosaurs. The tale focuses on a small hunting party that travels back to the late Cretaceous Era on a guided safari to hunt the ultimate predator - a Tyrannosaurus Rex - but when things go awry, a very real butterfly effect is put into motion that changes the future in ways nobody could have expected.
