This appears to be an Australian original cover. If so, it could be by Phil Belbin, who is reported by Kevin Patrick to have been Gredown's art director in the 1970s. Adapted from the Tom Sutton cover to Ghostly Haunts (Charlton, 1971 series) #49.
Adapted from Web of Evil (Quality Comics, 1952 series) #15 (June 1954) [as The Demon Coat]
