Two of these cards are available.  The one you see in this scan was mailed in 1905 with stamp and Boston postmark (Grade: 2, $6).  The other has more writing on the front bottom, from someone wanting to exchange postcards with a correspondent, and has stamp plus two overlapping 1906 postmarks (both readable) from sending and receiving offices.  We have resisted commenting much on this phenomenon, but we have plenty of proof here that USPS could move mail great distances in one day–back in those days (Grade: 2, $6).
