Jackie O’s late socialite sister’s classically cool and eccentric art and jewelry will hit the auction block in Manhattan next week.

The personal collection of Lee Radziwill — once a “style icon” and “muse” for Andy Warhol and Truman Capote — is up for grabs at Rockefeller Center, where it can be viewed starting Friday, according to Christie’s auction house.

The treasures belonging to Radziwill — who owned a home on the Upper East Side until she died in February at age 85 — are valued at between $200 and $60,000 apiece and range from a pair of sunglasses to high-end paintings. The auction is scheduled for next Thursday.

Her collection includes a quirky French sculpture of a toucan ($2,500–$3,500), an antique porcelain cabbage tureen from the mid-19th century ($800–$1,200) and a collection of her personal candid photos ($20,000–$30,000), according to Vanity Fair.

Other pieces include heart-shaped costume jewelry, art deco chairs and a painting of four tigers valued at up to $30,000.

In 2016, Radziwill told Architectural Digest, “When I buy something, I do so with the intention of keeping it forever.”

She was the younger sister of former first lady Jackie Kennedy.
