Carlos is rather significant to me as a comic fan and creator. His design of Saturn Queen from Superman/Batman has remained the definitive take on the character for me and is a staple in my plans.
Based on this post, I decided to put a used copy of the Superman/Batman Absolute Power trade on one of my online want lists. Thanks, Sarky.
Oh, and I did the same with both volumes of Superman Camelot Falls. I read that one years ago and thought Busiek's story was pretty good (nice use of Arion, as I recall) and Pacheco's artwork was great as usual.
Just free-associated Pacheco & Busiek also doing Arrowsmith. I'll have to see if my library has it. If not, then it, too, goes on my want list.
