The consistency of the design between passports is remarkable. They all follow a basic pattern: Country name at the top, centered logo, then the word 'passport' at the bottom. There are only a handful of countries that deviate from the pattern. It's almost like there is a universal passport design language. Does anyone know if there is a official specification counties follow? Edit: The international Civil Aviation Organization issues the specification. https://en.m.wikipedia.org/wiki/International_Civil_Aviation_Organization https://en.m.wikipedia.org/wiki/International_Civil_Aviation...
