When the syndicated Marvel Super-Heroes cartoon debuted in the fall of 1966, it was fashioned in such a way that each individual station could run it in whatever manner they pleased. As every story had been broken up into three 7-minute chapters, there was the freedom to mix and match segments, or to run an entire complete story each day. Most stations did the latter, dedicating a specific day from Monday-Friday to a particular character. One thing certain stations did was to have the cartoons introduced by their onw live-action host. This was typical for the cartoon spots of that period and would continue as a practice well into the 1980s.
In Boston, station WNAC chose to have the series introduced by an actor in a full Captain America costume. This was Arthur Pierce, who holds the distinction of being television’s first Captain America. (Though he was beaten to the role in cinema by Dick Purcell and a bevy of stunt doubles in the 1944 CAPTAIN AMERICA movie serial.)
Sadly, most of Pierce’s bumpers seem to be lost to history. A fragment of one did survive, taped off of the air on an 8mm camera by a fan. Reportedly, Superman creator Jerry Siegel wrote the copy for most of these spots.
