A stark white linen-weave card with a bleeding heart painted on it

From Elanthipedia

A pair of hands cradle the bleeding heart gently.

Within it, you read the following inscription:

   Once my heart did languish,
      Disconsolate and forlorn,
   Your gentle touch has healed me
      And my heart to yours is sworn.

The heart card has not been signed.
