The hidden date for this stamp can be found at the base of the shield in the coat-of-arms.
These two new stamps honour the provincial flowers of the fifth and sixth provinces to enter Confederation. Manitoba in 1870 and British Columbia in 1871. These stamps continue the floral emblem series scheduled for issue between now and the Centennial Year of 1967. Like most parts of Canada, Manitoba was first explored along its principal rivers, the Red and Assiniboine. Fur was the prize and the two fur trading companies, the Hudson's Bay and the Northwest Company, fought bitterly for the right to exploit the rich prairie area west of the great Precambrian Shield. By 1821, a secondary industry in agriculture had sprung up with the establishment of a colony along the Red River by Scottish settlers led by Lord Selkirk. After many struggles and tribulations, the nucleus of the present Province of Manitoba was purchased from the Hudson's Bay Company by the Dominion Government and, in 1870, the province entered Confederation. The Prairie Crocus (Pulsatilla ludoviciana) was chosen as the official flower of Manitoba in 1906. As with most of the stamps in the floral emblem series, the Manitoba and British Columbia stamps are being printed in three colours, in a combination of offset and intaglio printing.
