A 100 postcard collection of the iconic, bizarre and mind-blowing best of science fiction cover designs from 80 years of Penguin's history.

From the 1930s and 1940s and the world famous tri-band design, to the covers of the 1960s and 1970s inspired by surrealism, expressionism, psychedelia and pop art, this collection charts science fiction's emergence as a literary force while embracing the spirit of its pulp excess.

These 100 postcards feature covers for the heavyweights of the genre as well as highlighting some of the weirdest and most wonderful cult-classics you may or may not have heard of.

This collection will make you smile or shake your head in wonder - it is something to be shared and treasured.
