Superman #170 2001

Superman #170, published by DC in July 1964, features two notable tales. The first, 'Superman's Mission for President Kennedy!', sees Superman aiding President Kennedy's physical fitness campaign. This story is notable as it was famously delayed and then published as a tribute after Kennedy's assassination. The second, 'If Lex Luthor Were Superman's Father!', is an imaginative story where Lex Luthor attempts to travel back to Krypton to become Superman's father, a key moment for collectors interested in alternate timelines and character origins.
