100 Krónur Law of 1961

The "Law of 1961" designation refers to the enabling legislation that established the Seðlabanki Íslands as Iceland's sole note-issuing authority, replacing the former Landsbanki Íslands in that function. Notes of this series were authorized under that law but printed and circulated across a span of decades — this particular issue appearing well into the 1980s, long after the law itself was written.

Two printers are credited for the series: Bradbury Wilkinson and De La Rue. Both operated from British facilities, and plate use between the two firms was not uncommon for Commonwealth and Nordic central bank contracts of this period. Which firm printed a given note can usually be determined from the printer's imprint on the note itself.
