Weird Mystery Tales #21, August 1975. (One of my favorite Wrightson covers).
DC 100 Page Super-Spectacular #4, 1971. The back cover was Bernie's beautiful front cover reprinted without the logos and type.
Secrets of Haunted House #5, January 1976.
Secrets of Haunted House #44, January 1982. The date next to Wrightson's signature indicates this was drawn in 1972.
