The front of the card features the white mage's "perished" sprite and the following words: "No matter what happens to you..."
Flip it open and here's what you find:

My favorite aspect of this particular card is that it's appropriate for anyone. If you're a gay man and you want to give it to your same-sex sweetie, for instance, you imagine that the white mage is a guy. If you're a lesbian, on the other hand, you imagine that both the black and white mages are ladies. And if you're straight? Why, you imagine the white mage is a guy and the black mage is a gal (or the opposite, if you want), of course.
Who's to stop you?
