This study was inspired by a series of round postcards bought at the Bletchley Park gift shop, which provided one side of the book pages. They represent the many cogs that made up the Enigma-cracking machine: Bombe. The back of each postcard was covered by a graphic design I made inspired by the film Imitation Game (2014) starring Benedict Cumberbatch. The book is bound together by one brad-like device, so the pages can spread or stack depending on how you want to move them.
