Art and lettering is by the regular team: Mike Norton, Allen Passalaqua, and Crank!
This almost looks like it could be from a crossover with one of Mike's other books, Revival.
Speaking of Mike's other books, on sale right now is the first issue of The Answer, his creator-owned collaboration with writer Dennis Hopeless. Dark Horse Comics released it just yesterday, in comic book stores and via the Dark Horse digital app.
Here is a review of it at CBR.
By the way, It Girl #6 also got a great review from Greg at CBR.
"It Girl and the Atomics" #6 is a fun little side step away from the main action set back on Earth; if all the interludes are this enjoyable and well-put-together, I don't think anyone will complain too much about not getting another issue drawn handsomely by regular artist Mike Norton. Rich and Clugston Flores clearly had a good working relationship back when Rich was Clugston Flores' editor at Oni Press, and that has continued through to here. If you haven't tried out "It Girl and the Atomics" yet, this is a fun place to start.Read the full review here.
