After a great start with Alden McWilliams, Tom Corbett got stuck with John Lehti's deadly dull artwork. At least things perked up in the last three issues. Frank Thorne took over and made each issue better than the last. By the way, the Grand Comics Database seems hung up on crediting all the Corbett cover paintings to McWilliams. McW did paint covers for the two TC Four Color issues, but a comparison to the regular series covers shows these were all painted by someone else. The covers, some quite striking, look like the work of Dell's usual cover specialists.
