I'm not even sure if it's really Binary. It looks like her, but I can't say for certain. In 1984 I did a set of pin-ups for an issue of Marvel Fanfare that included Jean Grey, She-Hulk and Red Sonja. This would have fit right in with them except they're all super-skinny and this lady has just a little more meat on her bones. That leads me to think these were done a bit later, possibly for a commission, but for some reason, it was never completed.
I suppose it's even possible that I did draw a finished version. I don't think I did, but it was so long ago that I really can't say for certain one way or the other.
