Speculator Corner: Hulk 14-17
There has been a lot of fuss made over the MarvelNOW! relaunch, Thunderbolts, starring the General Ross Red Hulk, with the Punisher, Venom, Elektra and Deadpool as team members.
But it's not the first time this teaming has appeared. They were known as Code Red when they appeared in Hulk #14-#17, joined by Thundra and Crimson Dynamo, though missing Venom.
Right now those comics are lucky to sell for 99 cents each, though the variants or Hulk #14 do well.
Will that be the case for much longer?
