But is that because the painting was already famous and well known because of the theft (despite your not knowing about the theft)? That is, if you were a few hundreds years old and showed in your journals how you loved the painting in the decades before it was stolen, that would be significant. But saying you loved the painting before you know it had ever been stolen, but falling in love with it in the decades after it became famous because of the theft doesn't mean as much, does it?
