This undated photo provided by Doyle New York shows a 1991 thank you note from Jacqueline Kennedy Onassis to former New York City Mayor Ed Koch. On Monday Nov. 25, 2013, about 200 letters, books and other ephemera from the late mayor's home in Manhattan's Greenwich Village are going on the auction block. Koch, who led the city from 1978 to 1989 with a combination of determination, chutzpah and humor, died in February at age 88. (AP Photo/Doyle New York) less
