The banknotes of Denmark, 1972 series are part of the physical form of Denmark's currency, the Krone (kr). They have been issued solely by Danmarks Nationalbank since 1 August 1818. They are still valid but are no longer printed. The theme of the notes is paintings by Jens Juel (1745–1802) of various more or less famous people on the front sides and common animals in Denmark on the back sides.
