Here we go...
-How many bats are on the limited edition Batman print Stan drew? (do not count the bat symbol on Batman's chest)
-that number will take you to the corresponding issue in the Fantagraphics run
-On the cover of that issue, he is fighting an enemy.
-I'm looking for what kind of animal Usagi is riding while fighting that enemy inside the comic.
PM your answer and hopefully my math was correct

Good luck!
