You could make a pretty impressive collection of things with the Primadonna girls on them. There are these great unused large matchbooks I have listed. And then there are those wondeful small crown chips that feature her but are a bit tough to find. There is a great postcard on the Nevada Casino Ashtray Project with a picture of the front of the building with the statues of five of the ladys - and bunch of ashtrays with them.

There is also a five piece decanter set that matches the statues - very tough to find in good condition. I have to settle for the matches and the ashtrays for now but it does give me something to look for.
