I was in on that auction too. I only own 1 piece of OA so it really is not in "my wheel house", but Planets are always in my wheel house and Lost World is my favorite storyline in the run. That being said, I went stronger than you on it, but fell short by 3-4 bids.
one thing that made me try harder to pick this up is the "practice sketches" she did in the lower left underneath all the panels and a note that says"let little draw hydrator". Wondered if that was her hinting to editor or an editors suggestion to someone else.
