Jackie Kennedy’s personally-owned and -used large horse blanket made of soft fabric, measuring approximately 66 x 52, given to Bill Elder by Mrs. Kennedy due to their shared love of horses. Also present is an ALS to the blanket’s recipient referencing horses, signed “J,” one page, 5 x 8, White House letterhead, no date. A letter to Bill, in full: “I do wish you’d stop buying cars—apartments—horses—and the like and stay in the office—please.” Accompanied by a letter of provenance from Elder’s niece Eugenia Moore and a matte-finish 8 x 10 photo of Jacqueline and Caroline Kennedy riding horses together. In overall fine condition. William Voss Elder III, a retired Baltimore Museum of Art curator, assisted Mrs. Kennedy with his vast knowledge of antiques during her 1960s White House renovation. She became fond of him given their shared love of horses and similar backgrounds, and appreciated that he did not try to impress anyone or develop any airs while working for her in the White House. A unique collection associated with one of Jackie’s favorite activities.
