Russ Johnson set Mister Oswald in the fictitious town of Dippy Center. There were many reoccurring characters during the 82 years of the strip’s run, some of which you’ll see in the complete strips in the gallery, but these eight characters were the main ones. Mr. and Mrs. Oswald were in the monthly feature from beginning to end, while the other six characters were vital to the Mister Oswald during different parts of the strip’s long life.
