Otherwise, going by Mike's Amazing World's monthly llstings for not only DC & Marvel but also Gold Key & Charlton, it would appear that I didn't buy a single bloody comic in May 1971, except maybe for something from Archie or Harvey (not outside the realm of possiblity at all, but at this late date all their covers blend together for me, so I probably wouldn't recognize 'em even if they were pictured, too).
Which doesn't surprise me at all. For whatever reasons, about mid-1970 my comics consumption started seriously tapering off; by 1971 it would've been close to nonexistent. Maybe the 3-cent rise in cover prices didn't sit well with me; maybe I just didn't find the early Bronze Age very appealing after cutting my teeth on the late Silver Age. I know it wasn't the usual factor -- girls -- because I only turned 11 in 9/70.
As I've noted before, though, 1970 was the first year I started buying baseball cards, & with a 50-cent weekly allowance (which I think was still my going rate at the time) I could probably serve only 1 master. I didn't start taking any real interest in comics again till late '73, in the form of the Marvel sf titles Worlds Unknown & Weird Wonder Tales.
