Either of two answers is acceptable. One artist met John F. Kennedy in Palm Beach, Florida, and subsequently depicted JFK in watercolors based on her observations. Jacqueline Kennedy Onassis commissioned another artist for a posthumous oil painting that shows JFK gazing downward. Name either artist.
(If it helps, the former was married to the creator of the abstract painting Police Gazette.)
