Cz's as we all know, ar fond of anything late 80's and early 90's...
wear some Drakkar Noir, bring a mixed tape with the Smiths and the Cure,
Depeche Mode, and Nine Inch Nails on it...she will so be yours!
Cz's are also such Eurotrash, so have some decent old school Raver music
on it as well.
Other than that, if it has no STENCILLING MARKS on it, and no mention of Kansas City on it, then it has to be at least 5 or 6 years old, and proly more like 10 or more if it still has the old Cyrillic lanuage on it anywhere.
