In the space of about 100 years the Swiss bank note developed from a relatively modest piece of paper to a graphically and highly complex work of art.

The following illustrates this development:

The Interim Note The Notes from Ernst and Ursula Hiestand
The Notes from Hodler and Burnand The Notes from Eidenbenz and Gauchat
The 20 Franken "Vreneli" The Designs from Werner Jeker
The Contest of 1989
The Notes from Jörg Zintzmeyer
