“Mr. District Attorney” makes absolutely clear the differences between the 1940s comics and the 1950s comics. In the late 40s, it started off as an ordinary detective/crime solving comic, an adaptation of a radio drama. However, as the years went on, due to the nature of the culture of the 1950s, strange, surreal, and at times, silly situations began to creep in little by little. 

Eventually, we got Shep the Wonder Dog as a case’s star witness….

Before we ended with the Masked Secret Seven and an alien witness. 

Unrelated fun fact: in Canada, district attorneys are called “Crown Prosecutors.”
