That swipe file site is a treasure trove.
I'm surprised it doesn't have a huge section for Giffen.

Some similarities are probably coincidence. But the overwhelming abundance of identical layouts by Buckler to other artists is pretty beyond question swiping on Buckler's part.

I wasn't aware why STAR HUNTERS was cancelled, I thought it just wasn't selling. It wasn't a series I thought was particularly good or imaginative. Even though it had early work by Layton, Buckler, Newton, Hama, with writing by Michelinie.

That's hilarious about Buckler wanting to sue the COMICS JOURNAL. I recall an editorial cartoon in a 1980 COMICS JOURNAL issue, where it shows Neal Adams in the IRS talking to a tax agent, and the agent tells Adams he'd be perfectly within his rights to claim Buckler as a dependent.
