I started collecting business cards from famous people years ago, and I recently unearthed the business cards of Bill and Hillary Clinton (in case you didn’t know, Bill was the 42nd President of the United States. Hillary wants to be President, but hasn’t achieved that yet.)
Interestingly, these business cards are larger than standard size – they’re 3 7/8 x 2 1/2 “. Not particularly thick card stock, I’d guess 12pt stock.
They probably had more impressive cards for special people!
