here's an old note printed by de la rue giori security printers in lausanne, switzerland to display their security printing abilities to prospective clients. the front features johannes gutenberg, the inventor of modern printing. obsolete by todays standards, it's still a well designed, attractive note.
de la rue giori was sold in 2001 to kba security printing (koenig & bauer ag) and is now known as kba-giori. their more modern note, shown here, features jules verne and boasts over 90 security features. i've never seen one for sale, but i'm dying to get my hands on one!
