Spinach comics. You want a history of these things, go to some comics history site. I’m sure there are sites that lavish great affection over the series, and laud their educational intentions. I hated them. Not that I read them; no. But I hated them. These were legitimate comics. Adult-approved comics. Doctor’s office comics. Their very presence says “the comics you normally enjoyed are looked down upon here.” No superheroes, no ghouls, no fun, just guys in hats with feathers and what-ho and ships. Maybe pirates but don’t count on it.

This cover tells you all you need you know: it's about these four guys who were called the Three Musketeers. The ones on the right were twins, I guess.
