Playboy Aliases: Margaret or Marilyn?

I mentioned the other day that I was going to go through the vintage Playboy centerfolds to see what goodies might be there. Here's Miss February 1954: Margaret Scott.

Now here's the funny thing. Margaret is also the Playmate of the month just two months later, April 1954. But this time she's using the name Marilyn Waltz. And she's blonder, I think:


And a year later, guess what? Marilyn Waltz returned, to become the first of only two three-time Playmates of the Month (and our second Playmate named Marilyn in a single weekend):


Who was the other three-time centerfold? Well if her eyebrows were any good, you'll find out soon. Stay tuned.
