Check out my auction:
E3 2002 Nintendo e-Reader Card Promo Pack w/ Kirby Card UNOPENED & FACTORY SEALED! The rarest e-Reader cards!!

I know there are a few e-Reader aficionados here who might be interested in this...

According to the Collector's Closet column in the May 2005 issue of Tips & Tricks, it's the rarest North American e-Reader card pack ever made, and very hard to find nowadays. I haven't seen any on eBay forever. Might I add that the issue of Tips & Tricks with full-page feature on the cards is included in the auction, a perfect collector's companion piece!
