The Newport museum that was once the stately home of the Vanderbilts acquired a Sargent portrait for the home from an English collector:

A John Singer Sargent portrait of Cornelius Vanderbilt II, painted in 1890, has returned to The Breakers, the former Vanderbilt summer cottage in Newport, a National Historic Landmark maintained by the Preservation Society of Newport County.

The portrait was acquired in late May at Sotheby’s sale of American paintings, drawing and sculpture in New York City. The purchase price of $230,500 was financed from the preservation society’s collections reserve, supplemented by donations from Vanderbilt family descendants. The painting had previously been in a private collection in England.
