Four Color #866, Dec. 1957. Dell Comics. Script: Don Christensen; Art: Tony Sgroi
This Dell comic came out about the same time as the "Mars and Beyond" episode of Disneyland that aired on December 4, 1957. Like the comic, the TV show discussed the possibility of life on Mars and how would man would conquer and colonize the Red Planet. This was, of course, back when we actually thought that there would be a future.
