MEDFORD, Ore. (AP) -- Tribal officials on the Great Plains have objected to the plan of the Southern Oregon Historical Society to sell artifacts that include a shirt described as exquisite and dating as early as the 1830s.

The Medford Mail Tribune reports the organization, under financial pressure, has been selling off artifacts that don't relate to Southern Oregon history. The shirt to be auctioned in San Francisco was donated by a Grants Pass resident in 1957 and came from an ancestor who obtained it in Nebraska.

Steve Vance, historic preservation officer with the Cheyenne River Sioux Tribe in South Dakota, says the shirt seems to have ceremonial significance and is the kind of artifact tribes have been unable to get returned.

The paper says the collection is valued at $300,000 to $500,000.
