Can anyone confirm that the plane depicted is really a M-2 (really should not be listed as a Douglas DM-2 but an M-2; it messes you up when you search for it online). It started with a little thing sticking forward on a wing support near propeller that made me wonder if the plane was supposed to be flying (one would think it would go the other way if it was a loose thin wire or string). Much to my chagrin, I end up reading on Wikipedia that the O-2 was modified from a "two seater to a one seater to be a mail plane by Douglas. Plane looks like a 2 seater to me and not like the picture of the one seater M-2 that I saw but the pilot on stamp is "observer seat" in the stamp which is where they moved the pilot seat for the M-2. I will be kind of mad at Western if they took a picture of a person in the observer seat of an O-2 on the ground then called it a DM-2. I am mad at them anyway for calling a DM-2 because it made it hard to google. Actually, I am not even certain that it is a real picture since there appears to be two "windshields on the plane and neither one has two shields just one.
