Part of the 1972-1976 'Indians of Canada' series, 26,000,000 of these se-tenant Pacific Coast Indian stamps were released in 1974. On left are artifacts from the ROM and the Museum of Civilization: A Haida bentwood storage box (the cedar cordage was used to secure contents when in freight canoe transport), a Nookta whalebone club, a Haida halibut hook, a Haida moon mask, a Salish blanket, a salmon woodcarving and Haida and Tsimshian baskets. Right shows, `The Inside of a House in Nootka Sound', a 1778 drawing by John Webber. He was the official artist on Captain Cook's third voyage of discovery around the Pacific 1776-1780.
Another instalment from the 'Indians of Canada' series. On the left are Subarctic artifacts; a caribou scapula, bear skull, Cree drum, mitishiMontagnais woman's hat, and a model Chipewyan canoe. Ms. Nathalie GuĂ©nette from the Museum Of Civilization kindly tracked down the catalogue entries for these artifacts. The drum belonged to a Shaman and is made of moose skin, decorated with red ochre. The beading on the hat was attached with thread but strung with sinew. Based on the presence of sinew it is thought that this hat was created earlier than the collection date of 1875. But couldn't this beading have come from an older specimen, reattached to a new garment with more modern supplies? Was that common? 
On right is the, 'Dance of the Kutcha-Kutchin' illustrated by Hudson's Bay trader, Alexander Hunter Murray. It was originally printed in Sir John Richardson's 1851 book, 'An Arctic Searching Expedition''. He was searching for his friend and explorer, Franklin.
A philatelic cover from the Oxford Philatelic Society with the artifact stamp from the Algonquins subset. They items are: a Atikamekw birchbark basket, Ojibwa cradle, Montagnais snowshoes, Maliseet birchbark basket, Montagnais knife, and a Mi'kmaq birchbark basket with porcupine quills.
This is the first private cachet I have seen which features on an archaeological site! Too bad it preceded the Iroquois issue by only 3 years, as the site is Iroquoian, and not Algonquian. Occupied from c. 950-1250 it is thought to have supported 200 people, and was tapped into the wider trade network with the presence of Lake Superior copper, and Californian seashell. 
Neither the cover nor the insert is numbered, so I do not know how many of these were produced. To obtain modern Oxford covers, click here
