Or "Bettie" as today's NY Times article says was the real spelling.
I didn't know her name when I was a boy in the 1950s and discovered her open and friendly smile in her pin up photos in mens magazines of those pre-nudity—or any kind of too-much-information nakedness—times.
She was usually in a two piece bathing suit that couldn't even be called a bikini, because there was more to it than most bikinis. She had the kind of figure that seemed naturally beautiful then, before stick figure models became the norm. Curves in the right places, including her smile.
When she was rediscovered in the 1980s and later a film was made about her, I felt like what made her special back then was being misinterpreted. But in the end, I think I was wrong. I think her appeal was always her smile, which seemed to say, hey, it's okay to feel attracted to a pretty woman in a bathing suit or less. At least it's okay with this pretty woman. Enjoy. And we did.
