Leave it there always in memory of my visit; and whenever you look at it or show it to anybody you must let it remind you to be a good little girl.

Whenever you are naughty and someone points to that mark which your good old Santa Claus’s boot made on the marble, what will you say, little sweetheart?

Good-by for a few minutes, till I come down to the world and ring the kitchen doorbell.

Your loving Santa Claus
Whom people sometimes call
“The Man in the Moon”
