An unrepentant lifelong doodler and sketcher, Saint-Exupéry had for many years sketched little people on his napkins, tablecloths, letters to paramours and friends, lined notebooks and other scraps of paper. Early figures took on a multitude of appearances, engaged in a variety of tasks. Some appeared as doll-like figures, baby puffins, angels with wings, and even a figure similar to that in Robert Crumb's later famous Keep on Truckin' of 1968. In a 1940 letter to a friend he sketched a character with his own thinning hair, sporting a bow tie, viewed as a boyish alter-ego, and he later gave a similar doodle to Elizabeth Reynal at his New York publisher's office. Most often the diminutive figure was expressed as "...a slip of a boy with a turned up nose, lots of hair, long baggy pants that were too short for him and with a long scarf that whipped in the wind. Usually the boy had a puzzled expression... his boy Saint-Exupéry came to think of as "the little prince," and he was usually found standing on top of a tiny planet. Most of the time he was alone, sometimes walking up a path. Sometimes there was a single flower on the planet." His characters were frequently seen chasing butterflies; when asked why they did so, Saint-Exupéry, who thought of the figures as his alter-egos, replied that they were actually pursuing a "realistic ideal". Saint-Exupéry eventually settled on the image of the young, precocious child with curly blond hair, an image which would become the subject of speculations as to its source. One "most striking" illustration depicted the pilot-narrator asleep beside his stranded plane prior to the prince's arrival. Although images of the narrator were created for the story, none survived Saint-Exupéry's editing process.
