If you're a completist like myself regarding "The Walking Dead" #100, then you know as each day passes, we're a day closer to the unreleased Hero Initiative variants. While doing some digging to see if anything new had been released regarding this cover, I managed to find 3 more one of a kind covers that will go up on the auction block for the charity.
