This rare card is part of the general term used in collectables called ephemera, which
basically means paper that was never meant to be kept. Everything from receipts to advertisements to flyers and pamphlets to envelopes, ephemera was and is the day to day reflection of ordinary life. It is one of my personal favourites. Many people collect tickets from sporting events and concerts that they have been to. This is true personal ephemera.
So, climb aboard the ebay train, make your best offer and you too, could start your own ephemera collection. Or you could buy a lovely bottle of wine, a rare steak and some fine dark chocolate and enjoy a snuggle with your significant other. I bet they would appreciate if more.
Here's the link to the valentine above.
