A get well card was a type of personalized greeting that expressed the well-wisher's desire for the receiver to "get well" after an injury or ailment.
Following Tom Paris' 2376 incident with Alice, B'Elanna Torres gave Paris a get well card from Naomi Wildman, which contained a drawing of the two standing on USS Voyager's bridge. Torres then commented on the card's artwork, telling Paris that "it's a pretty good likeness of you, but I don't think she quite captured my eyes." (VOY: "Alice")
