Here's an image of the original Batman art by Perez which appeared in Comics Interview #78, published in 1990. It was included in an interview with Todd
Reis, who had accumulated quite a collection of Batman art by a number of
artists. Here's the excerpt dealing with the Perez piece:
Darrel L. Boatz (interviewer): Next we have a George Perez Batman, very
obviously CRISIS related.
Todd Reis: Right. It's sort of a fisheye look at the city with Batman
swinging towards you. He colored it interestingly. Personally, I think it
might have been better left in black and white.
Darrel: Well, but the red sky makes it obviously a CRISIS piece. I don't
mean to pry about how you felt about the CRISIS or anything, you already
commented on that about the Huntress-
Todd: I felt it needed to be done. I mean, I can really sympathize with the
way things were going with the stories upon stories and the revisions upon
revisions, and times change.
Darrel: I was wondering how your feelings for the CRISIS affected your
feelings for this piece?
Todd: It doesn't faze it, to me it's just a George Perez piece. In fact, I
don't think I've ever thought about it being CRISIS related myself. You say
"red sky," the same could be said of the piece Giordano did.
Darrel: Well, it's red sky with lightning and by George Perez.
