DC and Marvel weren’t the only comics I enjoyed reading and collecting as a kid. Dennis the Menace from Fawcett, the original publisher of Captain Marvel, was a favorite. Harvey had the Casper line of characters.
Harvey’s titles included Richie Rich and Wendy the Good Little Witch. If it’s possible to have a crush on a cartoon character, Wendy was my age-appropriate alternative to Elizabeth Montgomery in Bewitched.
Sid Jacobson was the editor and writer behind many if not most of those comic books. Thanks in part to a graphic novel he wrote about 9/11, Jacobson has an obituary in The New York Times.
