I've always just missed big stuff: could've seen bands like Nirvana and The Replacements with just a couple of people in the audience before they broke big. But I just missed it. For a variety of reasons.
But not comics in the early to mid 80s. I was there as daredevil, watchmen and swamp thing, batsman year one, and dark knight came out month after month.
It was awsome.
But back from my reverie and to your question Have no idea what dkr #4 9.8 is worth.
I paid about 525$ for #1 in 9.6 SS with Miller and Janson. (Bought from a boardie?) Forgot what I paid for blue label #1 9.8. Both first printings. Both bought about a year ago. And I have many, many copies of the 1-4 run raw. It's hard to see them and not want to buy them and give them a home.
