Newton in the RBCC fanzine issues did a lot of tributes to Golden Age characters like Starman. I like the Flash Gordon pages and covers he did there too, maany suitable for framing.

A minor correction, I said that was a Newton cover, it was actually page 1 of the interior story. I corrected that in my above post as well, and here's the complete story online:

Like I partly said, Newton from about 1968-1978 did work for fanzines and for Charleton, and then became a prolific contributor to DC from late 1978 till his death in 1984.
He did work in BATMAN 305-306, 328, 331-332, 337-338, 346, 352-357, 360-372, and 374-379.
And most issues of DETECTIVE COMICS from 480-526, and 539.
And BRAVE AND THE BOLD 153, 156, and 165.
And TIME WARP 1-5, and then a few stories in the revived MYSTERY IN SPACE 111-117.
Plus "Shazam" backups in WORLD'S FINEST 253-270, and 272-281.
And a few other stories in scattered issues. But that alone is a lot of work in just 6 years.

And yeah, I'm definitely getting old, at age 57 now. I still think of the comics from the early/mid 1990's as "the new stuff".
