FANTASTIC FOUR (1961) #252

Our heroes discover a primitive culture deep within the Negative Zone! At the Baxter Building, Alicia and Franklin have some unexpected company. Continuing The Fantastic Four’s journey throughout the Negative Zone, this time visiting the alien civilization of Ootah. * This issue has the curious novelty of being printed completely sideways, and read like a calendar! This issue also got approved by the Comics Code Authority (CCA), despite the fact that it shows little Franklin in danger at the hand of Annihilus and the Negative Zone foe even throws the boy brutally against the wall, apparently knocking him unconscious.
