There are also at least 2 more boys in pigtails.
First Buckwheat (pics 1+2) looking similar like Farina but mainly with smaller and looped pigtails here. Pic 1 colorized from movie “Divot Diggers” (1936)
I’ve also seen a pic of Stymie (pic 2) with long pigtails but they were probably just attached to his hat. Both b&w from unknown movies but most likely from earlier films.
Main entry, boy/girls rating 5 (incl. pulling at pigtails)
