I was never a big fan of Frank Robbins' comic book work but I did like his JOHNNY HAZARD newspaper strip quite a bit once i discovered it in the 1970s in THE MENOMONEE FALLS GAZETTE, a weekly newspaper that was ALL comic strips!
And those were the then-modern strips! Still to come in the 1980s were multiple format reprints of JOHNNY HAZARD from earlier peak periods.
Tonight, whilst rummaging through old issues of VARIETY online, I found mention of a planned live-action Haz series dating from 1962!
One interesting point here is that it's implied that Howard Liss was writing the comic strip. Liss was a writer who wrote in various fields over the years but he was, as near as I can tell, not known to be associated with HAZARD. It's possible that the Introductions to some latter-day collections I don't have talk about his involvement... but Jerry Bails' online WHO'S WHO lists Howard Liss's strip work only as seen below.
