Here's a little of the history of the man who was the Patriot, and gave up that identity to become Captain America!
All these appearances, and the Patriot never made a cover in the Golden Age, so settle for a few of his splash pages to show his original costume!
This was also the costume Rick Jones manifested him during the Kree-Skrull War (but that wasn't really Jeff Mace....).
1970s Revivaloriginal Captain America, the original Human Torch and Sub-Mariner formed in an issue of the Avengers during a time travel adventure), more classic Timely characters were given new life, detailing their adventures during World War II, this time as the homefront heroes, the Liberty Legion, including the Whizzer, Miss America, the Thin Man, Jack Frost, Blue Diamond, Red Raven and the Patriot...
their new Captain America and Bucky against the android, Adam II, who killed the second Captain America....resulting in Jeff Mace making the decision to take up the spirit of liberty, and become the newest Captain America, where he remained until he couldn't any more (with this history recognized in Captain America #215 in November, 1977), retiring to go back to reporting, and another man was assigned by the government to become the fourth Captain America.
End Of The Line
Life Of The Legend
...with the longest look back coming in Captain America: Patriot mini-series, with four issues from November 2010 to February, 2011, really getting into the mind of Jeffrey Mace and his added history!
Captain America History
...facing off against the dead villain in the odd Captain America's Weird Tales #74 (October, 1949), as the Red Skull got the lord of the underworld to bring Cap to hell for one last battle....(and the rest of the tales of this and the next issue were supernatural ones, not relating to Captain America). Through all this, Captain America triumphed....a Patriot (this time, represented by Jeff Mace).
