First appearance of the Black Panther. Tossed this one in as a prime example of what a successful Marvel movie can do to a comic. Seven years ago, Overstreet had this book valued at $700 in NM 9.2. Current Overstreet has it at $4,600 and that is way less than it sells for in reality. Crazy world.
Eventually, I will have all FF V1 comics scanned front and back on my website. What I have so far can be found here: https://dekventures.com/FantasticFour/fantastic-four-v-1-regular-issues
