It is possible that the splash page of this story is used as the cover of the Canadian comic Teen 'Venture (Bell Features, 1950 series) #17, but this needs to be confirmed.
It is possible that "Jon Jay" is a pen name or a house byline.
Only appearance of this "Electro" feature from Fox. Not to be confused with Fox's 1940 "Electro" feature (which was renamed "Dynamo" after one installment) or any other publisher's "Electro" features.
