The burglars also made off with surveillance tapes that might have caught them in the act.
Police released images of the art on Thursday, hoping someone might help solve the crime in Manhattan's trendy Meatpacking District.
Authorities estimate the home was burglarized last month, sometime during Thanksgiving week.
At the time of the break-in, owner Robert Romanoff was away.
Romanoff is president of the Nebraska Meat Corp. started in New York City by his immigrant relatives in 1905.
Also stolen from the five-story building in the Meatpacking District was pricey jewelry including Cartier and Rolex watches.
