Black Cat Comics #50 (Harvey, 1954)

A classic cover! Radiation-related covers from the 1950s are highly prized by collectors, and this ghoulish delight is simply one of the best! Not only is this pretty much universally considered to be the greatest, most over-the-top, and therefore most iconic pre-Code horror cover ever published, it's one of the most memorable comic book covers of any genre, from any period! And like virtually all of the Harvey artwork from Roger Hill's esteemed collection, this absolute classic has never been offered on the market. Original comic art truly doesn't get any better.
The Overstreet Price Guide attributes this to Warren Kremer, but most sources agree that it is Lee Elias.
