Three new-rate medium-value definitives featuring large mammals indigenous to Canada were issued on December 28, 1990. As the last set in a series which was begun in 1987, these three stamps bring the total number in the series to 19 different stamps, not including some paper and perforation varieties. The Peary Caribou (Rangifer tarandus pearyi), and endangered species living on the Queen Elizabeth Islands of the Canadian High Arctic, is pictured on the international rate 80-cent stamp. A subspecies of caribou, small, with pale colouration and narrow, upright antlers, these caribou are among several non-migratory species. Considered an endangered species by the Canadian Wildlife Service, the total population was recently estimated to be 3,600. The stamps in this series were all designed by Brian Tsang of Toronto. All three designs are available in panes of 50 stamps, while the 46-cent and 80-cent denomination are also available in handy packs of five stamps.
