Love Letters of Lesser Men Vol 1

In the movie for Sex and the City,  there is a scene where Carrie and Big are curled up in bed reading from a volume called "Love Letters of Great Men"
The book comes to play later in the movie when Mr. Big is trying to express how sorry he is by copying out each letter.
This prop, did not exist outside of the movie until enough fans had been asking for it that a publishing company finally put it together.  That lends a lot to how powerful the suggestion of something like that is.

The simple love letter.

Which proves, that something that powerful is never just simple. Even when you wish it were.
