I recently found a copy of the March 27, 1948 issue of Collier's, which includes an article written by Judith Crist on Dr. Fredric Wertham's crusade against crime comics. The complete article (along with the original accompanying photos of child models re-enacting the testimonies of children quoted in the article) is included below.
