Hundreds of items that belonged to civil rights icon Rosa Parks and have been sitting unseen for years in a New York warehouse were sold to a foundation run by the son of billionaire investment guru Warren Buffett, the younger Buffett said Thursday.

Howard G. Buffett said his foundation plans to give the items, which include Parks’s Presidential Medal of Freedom, to an institute or museum he hasn’t yet selected.

“I’m only trying to do one thing: preserve what’s there for the public’s benefit,” he said.

A years-long legal fight between Parks’s heirs and her friends led to the removal of the memorabilia from her Detroit home. It was offered to the highest bidder.

Parks, who died in 2005 at age 92, became a symbol of the civil rights movement when she refused to cede her seat on a Montgomery, Ala., bus to a white man on Dec. 1, 1955.

Buffett would not disclose the amount he paid for the items.
