As a longtime Playboy fan and subscriber, I knew all about this publication.
I am kind of surprised to had jump through many hoops, let alone find a contact all the way in Germany to find it.
Just a bit of background:
The original Playboy Catalogs were done by mail order. People would either call or send their orders by regular mail.
Back issues of the magazine dating back anywhere from 3 to 5 years, along with various Playboy Home Videos on VHS cassette and the always popular 'flats' or commonly known by myself and other loyal subscribers to the magazine as Special Editions.
The Special Edition you were referring to was exactly that. Lynne Russell talked about how she performed during HLN's heyday and her advice on what clothes make her feel sexy when not on the set

.
And FYI--there were other themed editions, including one with clothed pictorials of Vanna White and TPIR's famous "Barker Beauty" Dian Parkinson in the nude

.
Sadly, those issues ended in the early 2010's as Playboy turned to online subscription sites like the old time Playboy Cyber Club and in the last few years with the European run Playboy Plus.
My best advice in the future to boones and other fans, simply check eBay. There are tons of Special Editions there--from Playmates In Bed, Hot Housewives, Natural Beauties, you name it--they should have it.
Hope this information helps in the future.
