The sheet bas a window ( 5 ) of transparent plastics material which includes self-verification means ( 11 ) for verifying a security device ( 4 ) provided at a laterally spaced second portion of the sheet when the sheet is bent or folded to bring the window ( 5 ) into register with the security device ( 4 ). The self-verification means may be an optical lens ( 11 ) for reading an area of microprinting ( 10 ). In another embodiment, the self-verification means may be an optical filter ( 21 ) for viewing an area ( 22 ) printed with metameric inks. In other embodiments, the self-verification means and the security device ( 4 ) may be polarising windows ( 31, 32 ) or Moire inducing patterns ( 41, 42 ).
