Karen: Certainly a staple of the mid to late Bronze Age was Fred Hembeck, who lovingly made fun of both DC and Marvel. Hembeck's style was unique and instantly recognizable (the little swirls on the elbows and knees always got me) and he certainly had a thorough knowledge of comics history.
He had books published by Fantaco, like this one I found in the garage, as well as one-shot issues at Marvel, and features in different Marvel books. I'm not so sure if he had work published at DC -anyone?
This particular issue of "Dial H for Hembeck" from 1983 has an editorial from Fred praising the decision to kill off Captain Marvel, a funny article about conveniently ignored Superman/Superboy stories, a couple of pages of "The Many Faces of Jimmy Olsen" (it seems like he must have been transformed into something every other issue), a lot of one-page jokes about different characters, and at the end, a four page remembrance of comedian Soupy Sales. Interestingly, Hembeck draws Sales in a realistic manner -and it's quite good.
I used to enjoy seeing Hembeck's work pop up in Marvel books. Any thoughts on Hembeck?
