It has nothing to do with the all three main characters being on the page.
I only have the one Planetary page in my collection. Picking up another one (And helping a cat cause) sounds like it might be an okay idea.
Did I mention I got those two Hitch Stormwatch pages in the mail finally? Did I also mention that they came rolled up in a tube? They did. I've got about 100 pounds of weight on them right now. Once they're flattened I'll scan them up.
