Gilberton (publisher) in the context of Frawley Corporation

The Comics Code Authority (CCA) was formed in 1954 by the Comics Magazine Association of America as an alternative to government regulation. The CCA enabled comic publishers to self-regulate the content of comic books in the United States. The code was voluntary, as there was no law requiring its use, although some advertisers and retailers looked to it for reassurance. Some publishers including Dell, Western, and Gilberton (Classics Illustrated), never used it. Its code, commonly called "the Comics Code", lasted until the early 21st century. The CC formation followed a moral panic centered around a series of Senate hearings and the publication of psychiatrist Fredric Wertham's book Seduction of the Innocent.

Members submitted comics to the CCA, which screened them for adherence to its code, then authorized the use of their seal on the cover if the book was found to be in compliance. At the height of its influence, it was a de facto censor for the entire U.S. comic book industry, with most comics requiring a seal to be published.
