Under an agreement arranged by the New-York Historical Society, the New York State Attorney General and the auction house Sotheby’s, by which New York State institutions could pre-empt a sale of any of 183 Old Master paintings being sold by the society, Vassar acquired “Crucifixion With the Donor, Brother Amelius de Emaei,” by an anonymous painter of the Brussels school for the Frances Lehman Loeb Art Center.  As the highest bid for the work, estimated at between $80,000 and $120,000, exceeded the estimate at $184,000, the college was able not only to pre-empt the sale but to receive, under the agreement, a 3 percent discount. Vassar’s price was $179,050.     The New York Times
