Does this make our guy Mark IV?

Jules Rivera reprises the unusual ancestry of Mark Trail’s family originally presented in her first Mark Trail adventure, wherein several ancestors were shown to all share the same name and general look. I wonder if this also means they all married women named Cherry and adopted a kid they (re)named Rusty? Old “Forrest Trail” has Mark’s traditional double breast-pocket work shirt, and the Ur-Mark look. Good job, Jules.

I’m sorry, but is this the first time Mark has heard about his granddad’s work? How is it he has been following in the family business all this time, yet remained ignorant of grandpa’s achievements? Ain’t like he was some soldier from WWII unwilling to hash over old war stories. Wait! The first Mark Trail was a WWII veteran!

Art Department: How do you like the visual composition in panel 4 where Happy and Mark mentally “look back” at (or look forward at) Grampa Forrest at work?
