I'm confused by the term "original" Carte Blanche. You can still apply for a Carte Blanche at:

It is $300 a year and has more benefits (though I don't see many that are all that useful...at least not useful enough to justify the higher price).
Is there a different program that long-time "original" cardholders would have with different benefits/services?
