Anyone remotely familiar with horror comics will recognize the name Bernie Wrightson. In so many ways, his work is unparalleled in the industry. His meticulous cross-hatching and brushwork only got better and better over his career. Unfortunately we lost him just a few years ago in 2017.
While a lot of his earlier work appeared in numerous fanzines, this 3-page story from DC's THE HOUSE OF MYSTERY #179 (March/April 1969) is generally acknowledged as his first professional comic book story sale.
