Public Collectors:
From a review by The Horn Book Magazine on the back cover: “… So intense is the conflict, so satanic the power of ‘grass’ and ‘acid’ that the drama seems to proceed on two levels: the desperate struggle of Jim to save Kevin’s soul and sanity, and the universal war between good and evil.”
The ‘N’ is either an alternate or, more likely, a modification to make the psychedelic Electus a little less ambiguous. ‘T’ and ‘E’ appear to be edited for greater legibility and balance as well.
Edit: Scratch that. With that ‘E’, this is probably Electric Circus itself.
