The Green Lantern cartoons were from the 1967 Superman/Aquaman Hour of Adventure which was shown on CBS Saturday mornings. In addition to Superman and Aquaman were Green Lantern, The Flash, The Atom, Hawkman,Justice League of America, and the original Teen Titans Kid Flash, Speedy, Wonder Girl, and Aqualad (minus Robin, who was on ABC at the time on Batman). BTW, does anybody have the original intros for the Atom and Hawkman?? Haven't seen these on YouTube yet. Great stuff!!
