Czesław Słania engraved this note — a remarkable footnote given that Słania was Swedish-Polish and spent most of his career at the Swedish Security Printing House, where he engraved stamps for over 70 countries. By the time this series was produced, he was well into his eighties and widely regarded as the most prolific security engraver of the twentieth century. His involvement in Canadian currency work was a late-career commission that few collectors connect back to him.

The BC-66 series ran across two printing contractors simultaneously — BA International and Canadian Bank Note Company — which can produce subtle but detectable differences in ink density and registration between specimens from each plant.
