A house ad for DC 100-PAGE SUPER SPECTACULAR 6 (1971), with a wraparound cover by Neal Adams.

With an amazing set of reprint issues, including:

* JLA 21 and 22 from 1963, the first JLA /JSA Earth 1
and Earth 2 team up, that became an annual crossover event.
* A Bernard Baily Spectre story, from MORE FUN COMICS 55, May 1940.
* A Joe Kubert silver age Hawkman story, from BRAVE AND THE BOLD 36, July 1961, the third of Kubert's
six stories before Hawkman later got his own title.
* And golden age stories of Johnny Quick, Vigilante, and Wildcat.

I don't think in 1971 we realized often what treasures these stories were. The randomness with which these
stories were reprinted somehow made them more exciting.
