By now everyone is aware that the popular television series on AMC is what it is today because of the comic book created by Robert Kirkman, Tony Moore & Charlie Adlard back in 2003. The former exists because of the latter.
To say Image Comics hit it big with this series would be an understatement. As a result of the massive success The Walking Dead franchise has experienced on all fronts (comics, toys, television, etc) the price of issue #1 is extremely high. Also, in part due to the relatively low print run when the comic first hit stores (no one knew at that time the series would be a massive success).
The price is so high that a rare high grade copy (9.9 Mint), graded by industry leader CGC, sold on eBay on March 7, 2016 for over $22,000. Yes, that’s right, a modern day comic book sold for the price of a car. All I can say is Awesome!
