Captain Midnight #59

In "The Rainbow Sky-Writer," Captain Midnight and his sidekick Icky journey to Neptune after their clash with the villain Jagga, where they rescue a stranded child from an encroaching glacier. With the help of a hidden community of Netunians, they plan a daring mission to halt the glacier's advance using atomic bombs—before it triggers a planet-wide ice age. Leonard Frank handles both the interior art and the cover, bringing the interplanetary adventure to life with his distinctive style in this 1948 Fawcett classic.
