Fluorescent print on the 100-krone banknote

On the 100-krone note there is an invisible G-clef to the left of the portrait of Kirsten Flagstad. It is only visible when the note is exposed to ultraviolet light. Fibres in the paper and a narrow strip on both sides of the holographic foil strip will also reflect the light.
