As you can see, she was a brunette in those days.
Ms. Wilkinson proved to be so popular, she appeared again in Playboy in the August 1959 issue.
Although there were some pictures of her topless, you can see Playboy was much tamer then than it is today!
You can find several websites
about her . . . if you spell her name right! (no "e" in "Wilkinson.")
