The reason the Isz has a bruise is because of a joke i heard an editor once say when i was trying to break into the biz: "Everybody's got to take some lumps during their early years."
This was a "Chapter 1" un-published version of the original Worlds of Sam book.
I was drawing Isz's years before i created the Maxx. I could never find a good home for him though. For some reason the 'snoopy looking dude' on the right, never made it into the Maxx issues.
