If you're looking to send a Valentine with a difference then this 1940's Kiss Letterpress Postcard Set from Three Potato Four is worth a look.
The cards are inspired by original 1940's "Kiss" correspondence cards - leave an imprint of your lips at the top and then tick the relevant boxes to send a message to your sweetheart. The phrases are cheeky and full of fun - sure to bring a smile to the face of the recipient.
The cards are double-sided and printed on heavy stock. They come as a set of 5 (handy if you have more than one Valentine) costing $28 but you will need to pay the shipping to the UK on top which might make these a little too costly - decide for yourself here.
