Marvel Comics has announced a new imprint spotlighting the premiere issues of some of its most popular titles. The Marvel’s Greatest Comics imprint has five titles announced so far, with each going on sale for $1. The first title will be Invincible Iron Man #1, released on March 3, 2010. After the Iron Man reprint (which, as a special launch promotion, will actually be free), the line will move onto the first issues of Ed Brubaker’s Captain America run, Marvel’s (incredible) new Wonderful Wizard Of Oz adaptation, J. Michael Straczynski’s Thor and Garth Ennis’ Punisher Max.

“We’re proud of the books Marvel publishes and now not only are we giving retailers a great way to promote our top collections, but also giving consumers a chance to sample some of our top comics, maybe for the first time and at an unbeatable price,” said David Gabriel, Marvel Senior Vice-President of Sales & Circulation. “Marvel’s Greatest Comics represents one of the best values in comics today and with Free Comic Book Day only months after the initial launch, retailers will want to be well stocked.”
