Panel One: Ah, we're back to the good old days, of screwy perspective and anatomical impossibilities. And watch out in the bottom right corner Marion, Liz brought a Tribble with her!

Panel Three: Nice. It's a good thing Marion and Jim never had kids of their own, otherwise they'd know how much crap the "baby's things" consists of. /sarcasm
Panel Four: I'm having a hard time tearing my eyes away from that scary, yellow doll-thing in her arms. One grotesque, oversized limb is hanging out, possibly offering to help carry that suitcase.
Original art, revised art, recolored art... my world is freakin upside down. Tomorrow, expect the entire strip to be presented in claymation.
