Remember this photo? It ran in Dick Giordano's Meanwhile... column for DC's April 1983 cover-dated books.
Brooke--at the time a really huge star--was lending her fame to a PSA program trying to keep kids from smoking. Apparently there were kits put together to be given out in school, called "Super Kits", and starring guess who of the DC Universe. It even mentions TV commercials featuring Brooke and Superman, but I sure don't remember seeing any of those. I'd love to find one of the kits on ebay to see what it was all about.
I wonder what Brooke was thinking while reading this issue of Superman?
