Fifth banknote series, 1956
The four higher-denomination notes, which were issued from 1957, formed a thematic and formal unity for the first time in the history of Swiss banknotes, in that the portrait on the front is connected with the motif on the back of the note. It was the first time that a ten-franc note was not only designed and printed but also issued.
