Somehow, we have three of these German-made Hugh C. Leighton Co. cards 940, but even though the photos are the same, the reverse is different on each card.  The one you see in the scan is the best of them, unused. divided back (Grade: 2, $6).  Another was mailed in 1909, undivided back and with the message pencilled on the front bottom, stamp and full New London postmark (Grade: 2, $5).  The third–also undivided back–was mailed in 1905 and has stamp and three postmarks.  Two of those overlap on the back and another is just to the left of the lighthouse on the front (Grade: 3, $4).
