I hate (well not really) how Dejah Thoris has become like the de facto thicc science fiction cockslut when ERB repeatedly described her as petite. Even the original cover depicted her as looking fragile, thin and mysterious and like an Egyptian princess.

I never understood the men being buck-naked in Barsoom just because 'Mars is hot', for starters the planet is either rocky desert or crumbling ruins where you could easily get hurt, surely you should at the very least wear shoes? But more to the point, it's a martial culture where all the men fight, surely they would have figured out that armor would be sensible? The earliest art and illustrations did the sensible thing by drawing everyone like they came out of antiquity. The women can stay naked.
