Martin Lloyd traces passports back over three thousand years, using illustrations from his collection of historic passports to discover how passport design was influenced by a desire to confound the forger, how it developed from the handwritten paper to the technically complex document we use today and how forgers have responded to the challenge presented by secret safeguards. You will never look at your passport in the same light again.
