Good guess… but it’s a reference to the Radically Rearranged Ronin Ragdolls (RRRR.)

Oh this looks like it slaps!

Thanks! It does. So I co-created this comic with Kevin Eastman called DRAWING BLOOD, about a comics creator with a career roughly analogous to his. The Ragdolls are the main character's creation (Shane Bookman), and that's the cover of our in-universe comic.

Gonna give that a look!

The trade paperback has been out for about a year, and that covers issues 1-4, plus the pictured in-universe Ragdolls comic, and some other fun stuff. It's currently coming out (slowly) from Image, and issue 8 dropped last week. Right now we're aiming for a total of 12 (I'm writing #12 right now.)
