When I did a search for "Moronica" at "Comic Book Plus", I found another Moronica story, but this Moronica is a dog. The main character in this comic is "Corliss Archer". Comic Book Plus informs us that "Corliss Archer's appearance on the cover and interior stories is based on Janet Waldo, the actress who played the character on the "Meet Corliss Archer" radio series."*
Script and art are by Al Feldstein.
*Janet Waldo also did voice work for animated cartoons and is best known for being the voice of such characters as "Josie", "Penelope Pittstop" and "Judy Jetson".
