I had the pleasure of meeting Yvonne Craig some years ago. I can tell you she was a beautiful, charming, friendly, and "down to earth" lady. As teenager in the 60s, I have fond memories of watching her as "Batgirl" in the original Batman TV series. I can assure you she was the 'fantasy" of many a young man "back in the day".
Yvonne Craig, Rest in Peace.
