The historical significance of the first cartoon,
Cops Is Always Right (1938), is that it was the last of the Fleischer cartoons to feature the original ship door title page. This sequence opened approximately 65 cartoons, so the Fleischers likely thought it was time for a redo. "Cops is Always Right" was also the first cartoon to feature
Margie Hines as the voice of Olive Oyl, replacing the original Olive
Mae Questel, it's a role she would play for the next 5 years.
