A collection of 100 postcards, each featuring a different and iconic Penguin book jacket. From classics to crime, here are over seventy years of quintessentially British design in one box.

Ever since then, from their original – now world-famous – look featuring three bold horizontal stripes, through many different stylish, inventive and iconic cover designs, Penguin's paperback jackets have been a constantly evolving part of Britain's culture. And whether they're for classics, crime, reference or prize-winning novels, they still follow Allen Lane's original design mantra.

Sometimes, you definitely should judge a book by its cover.
