In order to celebrate the 200th anniversary of Abraham Lincoln's birth, Marvel comics had planned events to cover all of President's Day weekend.
Starting midday Wednesday, Marvel made the entire Spider-Man/Obama Inaugural Special available online for free at this location. Not only will all 6 pages of art be there, but every variant cover as well. So if you were stuck without your own copy (despite an unprecedented 5 printings) now is your chance to read the full story. They've also created 4 additional prequel pages that are available exclusively for this celebration.
But the real treat, Gettysburg Distress, comes Monday when they release an exclusive 6-page free digital comic featuring Spider-Man and Captain America as they witness Lincoln's historic Gettysburg Address. This tribute to the Bicentennial of the 16th President, the storyline is being written by Matt Fraction (whose work in Marvel Comics is top notch right now) with art by Andy MacDonald.
Marvel Comics has given Huffington Post readers an early look at the cover art of Gettysburg Distress below:
