This apparation of Mary was as the west had to receving an icon, direct from both God and Heaven. The tilma that the image appeared is still around to this very day.
Sorry.
It's not a "tilma" as in cactus fiber cloth, either.
Just ask the bishop of Mexico City (who was ex-communicated for telling the truth, as best as he could determine after careful exploration of the issues).
He wrote a book about it, though I do not at this time recall the title.
