During the summer of 1927, the celebration of the Diamond Jubilee of Confederation was fittingly carried out. A committee appointed by the government in connection with the celebrations suggested a special issue of postage stamps to commemorate the occasion. The subjects of these commemorative stamps centred around the statesmen and the events they commemorated. The stamps were bilingual with the words "Postes" and "Post."
This subject was also used for the 3-cent brown of the Confederation Issue of 1917. Additional portions of the original painting adding eight delegates to the group are shown in this stamp. The figure of Sir John A. Macdonald stands in the centre, and is his second appearance on Canadian postage stamp issues of 1927.
