I love, love, love Marina. She's without a doubt my favorite PMOM ever, and she hasn't done too badly for herself in the years since either. (She's a big wheel in Liberal Democratic politics in Brighton, England, these days - she's even been the mayor of her town - and she stood for Parliament at the last general election but unfortunately didn't win; you may remember that back when she was a Playmate she said she'd love to be the first one to sit in Commons.
Also, she's published several books on white magic.)
Here are some nice big pictures I've recently found from her Page 3 modelling days:
I also have scans of some of her non-PB magazine photoshoots which I'll put up in the near future.
