I have never been sure that pic 1 is actually MD. Why - because the other pictures of her show darker eyes and longer hair. Sure is a resemblance tho'.

She was in Playboy, not Penthouse, but she was never a centerfold, she was in a couple of those special newstand issues like Blondes, Brunettes and Redheads, or Nudes, or a Lingerie issue. (Pic 2 and pic 3)

We should lobby Playboy. Show us some of the other MD pics that you must have in your archives! You can't have taken only two! Please! She is far too beautiful to hide!

IMHO pic 2 is one of the all time greatest long-hair pictures!
