Please, I'd like to ask about this postcard of Jack Johnson and J. Jeffries, about its rarity (if you think it is) and potential price. The postcard is circulated, but it has something really fascinating from my point of view. The postacard was sent for someone called Agustín to a miss called Encarnacion Cuscurita, having summer holidays in the North coast of Spain, in San Sebastian. On the front of the card appears this date: July 2nd, Reno, Nevada. So, it was sent two days before the fight of the century. Please, take a look to the pictures. I wonder if PSA, SGC or Beckett would grade it.
