Visitors on a White House Christmas tour have noticed something missing—a rare 1963 greeting card that John F. Kennedy signed before his fateful trip to Dallas, Reuters reports. President and Jacquelyn Kennedy signed fewer than 30 of the cards, which were never sent out. "They are the most rare pieces of presidential Christmas memorabilia today," said one historian.
Laura Bush said that the White House has a copy of the card but did not include it in a display of presidential cards because it was unsent. Fewer than two dozen copies remain; one fetched $45,000 at an auction last year. The card features a holiday greeting and a nativity scene, the first religious image ever to adorn a White House Christmas card.
