I simply adore vintage illustrations depicting love and happy couples (in advertisements mostly). They are a little cheesy, but so very romantic. Don't deny it, you know you've fantasized about being swept off your feet (wearing a gorgeous vintage dress, of course!) and being kissed as if you were in a TCM movie.
A snippet from the poem "Camomile Tea" "We might be fifty, we might be five, So snug, so compact, so wise are we! Under the kitchen-table leg My knee is pressing against his knee." - Katherine Mansfield
