One of the Arctic's outstanding early carvers, his sculptural work Mother and Child was presented to Queen Elizabeth II by the people of Canada on the occasion of the 1954 royal tour. The image of this sculpture was reproduced on the 1968 Canadian 6-cent stamp.
Along with his other talents, Mannumi is well known among Inuit as a graceful dancer, thus confirming a long-held Inuit belief that a talented human is the true art object. Such a person should be capable of performing many skills - carving, storytelling, singing and dancing - outward evidence of inulariak, a worthy human being.
