Ms. Mercury

Dave created Ms. Mercury back when he was a fanzine artist, and she first appeared in a portfolio of his work which was published in Star Studded Comics # 15 (1969). She later made her first (and only) comic book appearances in his Futurians series, although she wasn't a member of the group itself. She's probably the rarest character which he chose to illustrate for the lettered and remarqued edition of The Uncanny Dave Cockrum Tribute, and I was the lucky recipient!
