Overstreet, was in the early days, the GUIDE..it has changed as Steve Geppi needs to do a complete revision of this product in order for it to become relevant again. When it was all and powerful, it in effect "slowed price increases down" and was an effective brake for the comic book market on over heating. It no longer has that power, as print media disappears, its survive or die...it must go online in the next 5 years.I recomment on this weeks SCOOP-4-16 the 53 minute steve geppi address to retailers this month....I learned a heck of a lot during that speech. At the height Diamond had over 7,000 accounts, today they are down to 3,000 and to get a idea of the state of the market coming up...read between lines on that speech, 2016 was great year, and 2017 was OK(4th best in terms of $ not accounting for inflation). The main Idea, expressed is dead right on...Time or the competition for your free time has never been so competitive with so many different choices, and how comic books have survived thru the 50's witch hunt, market crashes, etc is remarkable.
