I have a few, not really a collection, but just cards I have acquired over the years from people I've met in the casino world and elsewhere. (Mostly cause I'm a pack rat and hate to throw anything away). Your post got me to thinking that it would make a cool collectible, especially if you had cards from folks like Bill Harrah, Howard Hughes, Harold Smith, Milton Prell, Benjamin Siegel, etc. I wonder if you wrote to Steve Wynn or Sheldon Adelson if they'd mail you a card? Or maybe Robert Mayheu or Claudine Williams have some of their old cards tucked away somewhere?
