Hard Rock Vanity Nightclub Key

Yes, I'm a little biased toward Hard Rock keys (and Venetian keys...and Palazzo keys...and...) but I think this is a GREAT looking key!

Palazzo Adam Key

Above is an image of the Adam key from the Palazzo. I've heard that it's possible as few as 100 of these keys were produced (but I have absolutely no idea if this figure is accurate). I've heard that the key was produced for the bar mitzvah of Sheldon Adelson's son Adam (and while I've read a recent news story that mentions Adelson having a son named Adam and that they recently celebrated his bar mitzvah, the story mentioned that it was celebrated at the David Citadel Hotel in Jerusalem). Any information about this key would be greatly appreciated.
