[3] The first two issues of Marvel Feature were in the 52-page format, with the remaining pages filled out by a new Doctor Strange solo tale and a Sub-Mariner reprint.

Doing an Ant-Man feature was editor Roy Thomas's idea, but he found he did not have the time to write it himself and so turned it over to writer Mike Friedrich and artist Herb Trimpe.

Herb Trimpe explained that Mike was a graphic designer at the time and took on the inking job when his regular work slowed down.

Except for issue #1, drawn by Dick Giordano, the art for the series was by the creator most associated with Red Sonja, Frank Thorne.
