Passport Facts

How much do you know about your passport? The International Civil Aviation Organization has outlined the following rules about these little books:  Made of a material that bends rather than creases.  Stable in temperatures between 14F-122F degrees.  Readable in humidity conditions between 5%-95%. However, there are no stipulations about typeface, type size, font, and cover color, yet all countries have chosen shades of red, blue, green, and black for cover colors.
