Updated cover art credits from West Stephan (February 21, 2005). Originally credited to Bob Montana.
Originally credited only to Gil Kane.
Gil Kane and Pen Shumaker are credited by Jerry Bails' Who's Who as working as a team under the pen name "Pen Star". When comparing the story in issue #41, signed only by Kane, the inking, especially on faces, is very different, while figures and layout are similar, so he must have done pencils and Shumaker the inking.
