Check out Wings Comics for some pretty remarkable covers. Wings Comics had a moderately schizophrenic output for their covers. Some covers have very realistic airplanes, but for other covers you wonder if the artist had ever seen an airplane up close. There's oddball covers like the American seaplane shooting down a German fighter, as well as the one with the Devil! Near the end of the run, there were even a few scifi covers!
There are some strong females (like the gal in
#87 who's 'manning' a gun turret [albeit in a low-cut blouse, very short skirt, and stiletto heels]). Some of the damsels in distress covers seem to have a little bondage angle to them (like
#94). And what is it about women parachuting in dresses and spiked heels (see
#93)?!
I wonder which of the females on the Wings Comics covers is "Jane Martin: Ambulance Nurse" (redhead, blond, or brunette)?
I think that there are a number of the Wings Comics covers that would be good for TG storylines.
