Here, as promised, is one of Harry Harrison’s comic book pieces from the early 1950s. It was published in the October 1952 issue of Beware (#12), a horror comic which Harrison was also editing / packaging for Youthful Comics.
This story was definitely drawn and inked by HH, and it is believed that he also wrote the script.
