We changed the format from horizontal to vertical: a logical change as research revealed that people tend to handle notes vertically, and all machines accept notes vertically. We retained the width of the existing notes, but changed their length. The $1 bill became the shortest and $100 the longest, making it easier for people – especially the visually impaired – to distinguish between notes. Using different colors also gave each note a stronger individual identity. Imagery was selected to reflect the value of each note, with an educational element aimed at Americans and visitors alike. Each denomination features a black and white image of a particular aspect of American history or culture:
$1 – The first African American president
$5 – The five biggest Native American tribes
$10 – The Bill of Rights, the first 10 Amendments to the US Constitution
$20 – 20th Century America
$50 – The 50 States of America
$100 – The first 100 days of President Franklin Roosevelt
