The suppliers of Clemengold mandarins have put their contract for fruit pickers into comic book format, designed by South African lawyer Robert du Rooy.

Of 213 fruit pickers who were asked to sign the contract at its first trial, not one complained or asked for the previous (text) version. And their 4-hour induction was reduced to 45 minutes.

Thanks to document designer Stefania Passera for telling me about this at the PLAIN conference in September. You can see her lecture on visual design in contracts at Beyond the wall of contract text (in English, after a short introduction).
