Birds of Canada Series $50 Note
The $50 note issued in December 1989 was the first in the series to carry the cutting edge optical security device on its face. The note also features a portrait of William Lyon Mackenzie King engraved by Thomas Hipschen and a vignette of the Parliament Buildings with the Red Ensign flying. The back features an illustration of a snowy owl. For security reasons, the dominant colour hue on this denomination was changed from an orange-red to a blue-red. The note was printed by Canadian Bank Note Company Ltd.
