80 PAGE GIANT (1964-1969) seems to have changed its title to just GIANT for issues G-57 to G-89 (1969-1971). These likewise had a G-number in the series that doubled as an issue of BATMAN, SUPERMAN, WORLD'S FINEST, JLA, JIMMY OLSEN, LOIS LANE, or whatever series' characters were featured in a particular issue.


From 1969-1971. At which point they were replaced by the DC 100-PAGE SUPER SPECTACULAR line.
