That photo Goober posted is most definitely Christi Canyon. I still have the issue of Penthouse when she was a fresh faced 19 year old that was taking the porn world by storm then. Her breasts have deflated since but she is still amazing. Not bad for someone close to 50, eh ? 
Well, it does say "Christi Canyon" beneath her. I was just wonderin' if the one above it was Pandara Peaks, but apparently not.
When was the last time anyone saw Pandora, anyway? She was great. One of my all-time faves.
