According to the Grand Comics Database, “Ghost Woman” appeared in the 1945 giant one-shot comic, Star-Studded Comics (1945). The story is a one-off, not intended to be a series. Ghost Woman helps her husband get rid of some werewolves, then decides to go on to her final reward. There is a certain rough charm to the artwork, but it isn’t signed. I believe it is a shop job, probably using more than one artist.
Artist Bernard Baily, journeyman comic book man (the Spectre, Hourman, among others) worked in the field through much of the sixties, at least. He packaged one-shots during the war years and after in a comics shop business, Bernard Baily Studio, with Mac Raboy. They used different names for publishing companies. My belief is that they contracted with businesses that had paper rations, which during the war were needed for printing...even for stuff like comic books.
