Another issue I skipped at the time. About the best I can say about it is that Calnan's inks work better with Dillin's pencils than with Swan's. Gives the whole thing almost a Dick Giordano look.
Plotwise, basically the bad guy uses astrology to figure out Superman's secret identity. Along the way, we learn that Clark's birthday is not the same as Superman's...at least as far as Bob Haney is concerned.
