Joan Rivers' $28 million Upper East Side penthouse sells after 140 days on the market

The late Joan Rivers' 5,100-square-foot penthouse on Manhattan's Upper East Side has found a buyer after only 140 days on the market, according to The New York post.

The triplex apartment, known as The Spencer Condominium, has four bedrooms and five bathrooms. The pre-war building even includes a private elevator that goes straight to the penthouse.

Rivers had relisted the apartment many times over the years, most recently in 2012.

Leighton Candler of Corcoran Group Real Estate handled the listing.
