I have a run of DC covers on the way for a 5-issue arc of JLA Classified (Issues 50-54, drawn by John Byrne), the first of which is pictured here. I spent some time on a background, but wasn't getting what I wanted. I wound up erasing it all, and DC and I agreed that the white looked good, so I threw in the lasso in the BG and called it a day. Sometimes keeping it simple is best.
I'll post the others as they are released for solicitation.
