Postcard Thank Yous

I was thinking the other day how it would be neat to have a postcard thank you custom made so its from your honeymoon destination? Whether its a vintage illustration from Hawaii or a beautiful photograph of Paris... these could be pre-designed and sent out while you are on your honeymoon. Each postcard could have a relaxed travel message as well as a lovely thank you message! The overall design could even include certain graphics, fonts and colours from your wedding invitations and stationery. I've gathered a few vintage images that may inspire such project.
