The first and comparatively small printing of this stamp was found to contain a minute error shortly after it was issued. The accent over the second "e" of the French word "Exprês" was circumflexed instead of grave. This error, corrected in the new die, is the first in a Canadian postage stamp.
Aerial view of Quebec City looking northeast, showing the Plains of Abraham in the foreground. Superimposed on the picture is a drawing of the D.C. 4-M airplane, which at the time of the issue was under construction in Montreal for use on the trans-Atlantic mail and passenger route, and on the trans-Canada run. At that time, it was the most recent development in Canada's transportation industry.
