Crime Suspenstories #22 (1954)

Published from 1950-1955 by E.C. Comics, Crime Suspenstories, though not as infamous as E.C.'s better known Tales From the Crypt, is still one of the most controversial comics titles of all time.  Along with other adult-themed titles of the 1950s, Crime Suspenstories was targeted for censorship by Comics Code Authority following Dr. Frederick Wertham's Seduction of the Innocent, which alledged that comics as a whole contributed to juvenile delinquency and the sexual perversion of minors.  Following a series of Senate subcommittee hearings, E.C. comics was forced out of business as the subject matter its core audience demanded could not be published in such a matter as to earn the Comics Code Authority seal of approval.  This cover by artist Johnny Craig represents a focal point of that controversial time.  

Batman #15 (Vol. 1, 1943)

Though a constant in the D.C. Universe for more than fifty years, Batman, perhaps more than any other comics character, has existed in a constant state of change.  The character's origin story, one of the most well-known in pop culture, has not even proven immune to re-imagining with this fall's Batman R.I.P. storyline.  That being said, some may cry foul and error at the cover image above depicting Batman happily manning a machine gun while Robin feeds ammo dutifully, as any young ward would.  Interestingly enough, Batman began his comics life using a gun.  In his early adventures in Detective Comics and the first several dozen issues of the Batman series, the Dark Knight frequently used guns of various sorts, even having a vehicle-mounted machine gun attached to an early model Bat-Plane.  So, it should not be surprising that with the American war effort against the Axis powers in full swing in 1943 that the Bat would frequently be shown, at least in cover art, as fighting in the same style as the US soldiers on the front line and encouraging those on the home front to buy war bonds.  In this case, it is the classic lines of cover artist Jack Burnley that portrays the Dynamic Duo happily doing their part for the war effort, capably shilling for war bonds and fighting the forces of facism at the same time.
