 One of the more controversial aspects of Power Comics was the relative lack of credit given to Marvel Comics and the American creators of the material used.For the first few weeks of the Marvel reprints the company was not acknowledged at all, but Odhams then had a change of heart and published a letter from a reader pointing out the origin of the strips.But, throughout, Marvel credit boxes containing the names of Stan Lee and collaborators such as Steve Ditko and Jack Kirby were invariably deleted from the splash pages; the space they occupied was either left blank or covered with drawn-in artwork.
