Julie Newmar Never-Before-Seen PHOTOS Released

Back in October 1958, well before she ever donned a pair of cat whiskers or rolled the "r" in the word "perfect," Julie Newmar (aka TV's Catwoman) was an up-and-coming star about to embark on a high-profile photo shoot for one of the world's biggest magazines, some of them never seen before until being published in this gallery. It was an afternoon that Newmar, then 25, still remembers vividly. Newmar, who is soon to publish a new book, The Conscious Catwoman Explains Life on Earth (available for sale through her website) recently sat down to reminisce about that afternoon in New York City ... that afternoon she was in LIFE Magazine.
