Rivers' passing has left a big hole in the comedy world, one that has yet to be filled with the sort of gregarious personality she brought to the stage and the red carpet.
And it has also left her penthouse condo in New York's Upper East Side without an owner.
The four-bedroom, 4.5-bathroom unit at 1 East 62nd Avenue is on the market for US$28 million.
Built in 1903, in a building that is considered "one of the opulent mansions of the Gilded Age," the apartment boasts 11 rooms in total, with "meticulously restored architectural details, ornate décor and double-height entertaining rooms."
One of its grandest features is a ballroom and music room with 23-foot-high ceilings, which allow entertaining as befitted one of the world's greatest performers.
The apartment also has south and west facing views of New York, a terrace where you can overlook Central Park, and two-bedroom guest quarters.
