Fred Hembeck's comics were Da Bomb. He did a strip in the late 70's DC comics on the "Daily Planet" page (like the one above) each week, for that week's comics. The Planet page was a little hype about upcoming books, plus "Ask the Answer Man". (Hey, this was pre-internet, I wasn't even old enough to know about The Comic Reader or RBCC or anything like that yet.) Fred did a half dozen or so Legion-related strips, and had his own magazine from Fantaco over the years - some of it new, some reprinted from Comics Buyer's Guide. More on that eventually.
