For most of the latter half of the 1970s, DC and Marvel were experimenting with unusual formats for their comics in an attempt to find something that would sell. Comic sales generally were very low, with unsold returns running as high as 70%. One of the most fondly-remembered of these experiments was the tabloid comic. Huge in size (around 10″x15″), these comics are a joy to behold. They were mainly used to reprint existing material but there are a few originals, such as Kirby’s Captain America’s Bicentennial Battles and Superman vs. Muhammad Ali.

Following a tip-off in Back Issue magazine, I’ve happily trawling through this site — a veritable treasure trove of memories:
