The Royal Mail has revealed images of what is thought to be the world's most expensive Valentine's Day card.
Dating back to 1790, the intricately designed Valentine Card filled with heartfelt messaging would get up to 4,000 Euros if auctioned. That is around $5,258 US dollars.
Today it is currently housed at the British Postal Museum and Archive and they have no plans of selling the card.
The card is a handmade puzzle which unfolds to reveal poetic messages. Very different from today's card with short messages in them.
