Superman and all related etc. is the property of Time-Warner and DC Comics.
Here I referred again to "New Frontier" screencaps, as well as an old drawing of Lois from the early '70s (don't know who the artist is that drew it originally), and also gave her outfit a color scheme reminiscent of the usual brown and green outfits she wore in the Fleischer shorts. I have to admit, the colors of her outfit stymied me a bit, till I settled on referencing the Fleischer cartoons with colors that seemed a bit more practical and down-to-earth in comparison to Clark Kent's drab, colorless business suit and to the explosion of red and blue that is Superman's outfit.
Also, in that old early-'70s drawing, Lois was wearing short-shorts and go-go boots...which gave me all the more impetus to draw the woman wearing pants for once.
