In his introduction to his graphic novel "Yossel", Kubert wrote, "I got my first paying job as a cartoonist for comic books when I was eleven-and-a-half or twelve years old. Five dollars a page. In 1938, that was a lot of money". Another source, utilizing quotes from Kubert, says in 1938, a school friend who was related to Louis Silberkleit, a principal of MLJ Studios (the future Archie Comics), urged Kubert to visit the company, where he began an unofficial apprenticeship and at age 12 "was allowed to ink a rush job, the pencils of Bob Montana's feature "Archie"". Author David Hajdu, who interviewed Kubert and other comics professionals for a 2008 book, reported, however, that, "Kubert has told varying versions of the story of his introduction to the comics business at age ten, sometimes setting it at the comics shop run by Harry "A" Chesler, sometimes at MLJ; however, MLJ did not start operation until 1939, when Kubert was thirteen".
