• The New York Post letter was sent in a pre-stamped USPS envelope. **
• The New York Post address was written in block-style, all-caps letters that slope down from left to right. **

• The New York Post letter is the only known anthrax letter that was not sent to a specific individual. Instead it was sent to the unnamed editor of the New York Post.
• It appears that the anthrax perp most likely got the New York Post address from the newspaper and not the Internet. A very similar address for the New York Post can be found on the letters to the editor page of each issue of the New York Post:
  
  

  Editor New York Post 1211 Ave. of the Americas New York, NY 10036

  vs.

  The Editor The New York Post 1211 Avenue of the Americas New York, NY 10036

  
  
  The anthrax perp dropped the word "The" from the first two lines of the address and abbreviated "Avenue" as "Ave.". A similar address does not appear of the New York Post Web site.
• The envelope was never opened by the New York Post because it did not contain a return address and was not sent to a specific person.
• The envelope was discovered on the evening of October 19, 2001.
• The first person infected by New York Post anthrax letter was Johanna Huden, assistant to Editorial Page Editor Bob McManus. She first noticed a skin infection on September 22, 2001.
