Except for the boom years in the early 1990s, the title's popularity has actually waned. That this hasn't caused a drop in prices seems to defy economic logic. Even the dramatic plummet in demand for Spider-Man from 1994 to present day has been accompanied by more than a doubling in monthly prices from $1.25 to $2.99. What gives?
The answer the writer gives has to do with the the Federal Reserve and I may very well be wrong, but I get the sense that there's a gold-standard subtext in there somewhere. Whatever the case, it's a fun read.
In other comic book news, I did a little piece on the Jerry Siegel Superman decision last week that some of you might be interested in. It's a really fascinating bit of IP jurisprudence.
