A watercolor by Jacqueline Kennedy Onassis is being auctioned along with a Cartier watch she wore for years.

Christie’s said Thursday that the then-first lady, who painted as a hobby, created the artwork in 1963 as a gift for her brother-in law, Stanislaw Radziwill.

Radziwill gave her the watch.

Both commemorate a 50-mile hike that Radziwill undertook as part of President John F. Kennedy’s physical fitness initiative. The first lady briefly joined the hike.

The painting depicts Radziwill walking with a Kennedy family friend.

The items are being offered as a single lot at a June 21 sale in New York. The presale estimate is $60,000 to $120,000. 

The seller is anonymous. Part of the proceeds will benefit the National Endowment for the Arts.
