The hidden date for this stamp can be found in the tip of the shield in the coat-of-arms.
Along with the present provinces of Ontario and Quebec, Nova Scotia and New Brunswick were the first of the British North American colonies to unite and being about the Confederation, known as Canada. The two new stamps being issued by the Post Office to commemorate this historic fact, continue the floral emblem series of postage stamps, scheduled for issue between now and Canada's Centennial year of 1967. In September 1864, at Charlottetown, delegates from the Maritime Provinces met with a view to forming a Maritime Union. While in session, they were joined by delegates from what is now Ontario and Quebec and union of all the British North American provinces was considered. The Quebec Conference followed later in the same year when the Seventy-Two Resolutions, the basis for Canada's Constitution, were drafted for presentation to the British Government. In 1936, the purple violet (viola cucullata) was officially adopted by New Brunswick as the floral emblem of that province. Instrumental in the choice of this flower as the official provincial emblem were the Women's Institute, the school children and the Lieutenant-Governor, Col. Murray MacLaren. The two stamps are being printed by a combination of the intaglio process with complementary colour work done by the offset process using hand engraved masters for the original plates. This combination of printing methods is relatively new to Canadian postage stamps. It was used for the Peace stamp and the floral emblem stamps of Ontario and Quebec. The stamps are being engraved and printed by the Canadian Bank Note Company Limited of Ottawa based on drawings supplied by the Dominion Bureau of Statistics.
