Wow!

I didn't see that one coming. His first pro work was only published in LEGION 3rd series (beginning 1984), so you're right, not that old, only 61.

Lightle's art is very detailed and beautiful. I first recall him doing about a year's worth of LEGION after Giffen's first 5 issues on the 1984 Baxter series. And his 4-issue DOOM PATROL miniseries, and BATMAN 400. There's a checklist of Lightle's work at the Wikipedia link.
