Everyone has a date on which they celebrate their yearly birthday. But this is not necessarily the case with comic book characters. Their dates of birth are usually shrouded in veils. In the Disney universe you will only find three characters whose birthdays are officially recognized. And none of those three (Donald Duck, Mickey and Minnie Mouse) started their lives as babies. They all entered the scene as adults!
How does one establish a plausible date of debut for the characters Carl Barks used in his comic books? Well, one could simply take the date when the first story for a certain character was created - which in practice constitutes the date the story was received at the publishing company - and let that particular date be the day of debut. And if the character was 'born' in a cartoon, the first release date would be the date to choose.

Barks used many recurrent characters in his stories. Some were his own creations, whereas others were taken from existing comic book and cartoon universes. The total number of characters and groups of characters falling into the mentioned three categories - 60 in all - are presented in the sub-pages with their date of debut as well as a mentioning of their individual debut in Barks' stories.
The listings enable you to clearly see the order in which the characters had their debuts, and you may occasionally be surprised to learn when some of the characters emerged compared to each other. Who knows, you may discover that one of the characters' birthday is the same as yours! Enjoy...
