I looked up Garcia-Lopez on GCD. Here's a list of his work:

www.comics.org




I recall best his covers for ACTION COMICS and SUPERMAN FAMILY in the late 70's/early 80's.

Particularly nice, I thought, are his 3 covers for UNTOLD LEGEND OF THE BATMAN 1-3

And a series I'd like to check out, a 1992 three-issue TWILIGHT series he did, scripted by Chaykin, pencilled & inked by Garcia-Lopez.

And I'd forgotten that Garcia-Lopez did two big tabloid books:
LIMITED COLLECTOR'S EDITION C-54 (Superman Vs. Wonder Woman, 82 pages!)
and
BATMAN VS THE HULK ( DC SPECIAL SERIES 27, 64 pages)
