Lady Luck Bettandorf uses many interesting images on its chips. First, the Roger Craig Sports Bar chips have the San Francisco 49er logo. I'd be surprised that the NFL would give them the OK for this.

Second, their Millennium series of chips has pictures of many presidents and other celebrities from the 1900's (Chaplin, Babe Ruth, etc.) I'm sure that the celebrity's representatives had to give consent to be used, but are the predident's images fair game to anybody?
