Issued in 1958, this 5-cent Canadian stamp marks the centenary of the nation’s petroleum industry (1858–1958). The design contrasts an early oil lamp, symbolizing the dawn of oil use, with a modern refinery depicted within a stylized drop of oil, highlighting technological progress. Printed in olive green and red, it celebrates both industrial innovation and Canada’s historical role in pioneering petroleum extraction. Designed by Harvey Prosser, it stands as a classic mid-century commemorative reflecting post-war industrial optimism.
