The cover for Blue Circle Comics #4 was put on several different remaindered comics. Indexed here is what appears to be an otherwise unreleased issue of Martin Kane, Private Eye (Fox, 1950 series). Other known variants include Colossal Features Magazine (Fox, 1950 series) #3 (with the Bugsie Siegal overprint on cover, see cover scan). Contents have nothing to do with the cover.
Art appears to be by Pete Morisi. In panel #3 of page #2 there's a show poster in the background and on the top you can see "Morisi" written.
movie tie-in (?) as splash page announced Willaim Gargan as Martin Kane.
