Here's a Mark Evanier column about the very first San Diego Comic Con (1970) and his friendship and Con attendance with a friend named Mark Hanerfeld. Who was an assistant editor for Joe Orlando at DC from 1971 into the mid 1970's.

Who, a surprise to me, with a photo of Hanerfeld from the 1970's period linked above, was the visual inspiration for HOUSE OF SECRETS host character Abel.



It must have been gratifying to be splendidly rendered by the likes of Wrightson and Kaluta.
He appears on the opening intro splash page of HOUSE OF SECRETS 92, the issue that introduced SWAMP THING. And as I said in the Wrightson (R.I.P.) topic, the interior story used photo-reference for its primary characters of Michael Kaluta, Louise Jones, and Wrightson himself.
