Secret Avengers Vol. 1 #16 Comic Book – Near Mint Condition

“SUBLAND EMPIRE”
Run the mission!  Don’t get seen!  Save the world!  A secret city buried one mile under American soil is discovered through the leakage of Von Doom radiation – a type of energy emitted only by time-travel devices.  So the Avengers head underground to a weird metropolis forgotten about for decades, because a time machine in the wrong hands is the worst kind of WMD imaginable.
