Starting from the beginning, the card was mailed from Cardiff on 23rd September 1904 (stamp and two postmarks show this) to Buffalo, New York, where it arrived on 1 October, with another full postmark placed there.  Pattie was the original sender, and this is one of those cards where it was OK to write the message on the reverse for inland postage but not if the card was going abroad.  Which it was.  See also our entry 20560018.  Grade: 3
