DC Comics is still the market leader. The break in style and theme starts in April 1970 with their issue # 76 of the Green Lantern magazine, the first with the dual title Green Lantern - Green Arrow.
The character of Green Lantern, hyper-muscular in his costume like Superman's, is a veteran of comics. With the cover page of # 76, everything changes. He breaks in an angry gesture the lantern which assured his magic powers for 30 years. His face expresses hatred but all his violence is directed against evil. He even protects the adolescents against their will.
The rhyme of his speech is a profession of faith: 'In brightest day, in darkest night, no evil shall escape my sight'.
The regulatory authority for the morality of comic books, the Comics Code Authority, agrees to open the stories to social problems. The comics are permitted from 1971 to discuss drugs, alcohol, political corruption and environmental pollution with the absolute condition to show them as harmful.
Green Lantern - Green Arrow devotes his issues 85 and 86 to the drug. The mayor of New York is delighted but teenagers are not fooled. The commercial failure leads to cancel the title after the issue 89.
The original drawing by Neal Adams for the cover page of # 76 is estimated $ 300K for sale by Heritage in Beverly Hills on November 20, lot 92004. I invite you to watch the video shared on YouTube by the auction house.
