Two items signed in ink or ballpoint by Gene and Carolyn Shoemaker and David Levy, the discoverers of Comet Shoemaker-Levy 9, a comet that broke apart and collided with Jupiter in July 1994: an off-white 5 x 3 card, with each dating their autograph to November 26, 1994; and an FDC with a cachet honoring the Palomar Observatory. In overall fine condition.
