An early Great Lakes Anishinaabe carved serving bowl in original surface.
Formed from the trunk of a red maple tree, the profile is of a standard utilitarian form with a deeply tapered body terminating in a smaller, sharply cut foot. A hollowed interior is gauge carved by hand with the use of a scorp tool. Thousands of fine rigid tool marks are evident and raised, providing visual evidence of intense hand manufacture.
A small section of tree bark remains on the exterior due to producing a bowl from a 23" thick tree and being of a certain capacitive size while maintaining the required thickness to preserve structural integrity. 
Another surviving example with a flat rim and sharply tapered body is identical in manufacture and survives in the National Museum of the American Indian, collected directly from reservation by notable anthropologist Fredrick Johnson and coming directly from Ansishinaabe tribal areas during one of his several Heye Foundation sponsored trips to Canada. 
Survives in an overall excellent state of condition, exhibiting a small shrinkage crack (shown) being consistent with age, structural design, and use. A wonderful example of handcraft with impressive and simplistic form boasting its size at an impressive 23" in diameter with a full inch of shrinkage. 
Great Lakes Anishinaabe in origin, Parry Island, ON. Ca. 1780-1830. 23"W x 6"T.
