Cards in sleeves

This Edward Bawden design for Fortnum's Easter catalog is such a wonderful idea for a Valentine's card. As you pull the insert out, the hidden panels are revealed and the picture shifts. This could be quite nice as a tulip tree that blooms, lovebirds that fly, red books that fall off a shelf. This would also be a lovely way to wrap a book or a box of chocolate. I might try this with one of my messed up boxes.
