This is Kanigher's last issue, as editor or writer, until the end of 1972 when WW comes back in her star-spangled outfit.
Credits for pencils and inks confirmed from Julius Schwartz's editorial records, provided by DC Comics (added by Gregory Fischer, May 2009).
This issue refers to the "one day a year" WW loses her powers, something that was referred to back in (iirc) "The Human Charm Bracelet" back in #106. Either it's been a loooooong year, or WW sat out the other powerless days.
