With Marvel finally releasing their Phase One box set today, we’re starting to get a look at some of the extras included on the Blu-ray collection.  Earlier we got a sneak peek at a Phase Two featurette, and now some possible concept art has landed online that may or may not be included in the set.  The artwork provides us with a look at Cap and a transformed Bucky Barnes doing battle in Captain America: The Winter Soldier, and also gives us a number of glimpses at director James Gunn’s absolutely massive-looking Guardians of the Galaxy.

Hit the jump to take a look at the possible concept art from Marvel’s Phase Two.  Captain America: The Winter Soldier opens in 3D on April 4, 2014 and Guardians of the Galaxy opens in 3D on August 1, 2014. [Update: A few more concept images from Captain America: The Winter Soldier have made their way online and are now included after the jump, including a first look at The Falcon.]
