Polarine From Standard Oil

Even though this postcard is of a Detroit city bus, it was mailed from and to Kansas City. The postmarks, for sending and receiving are both "KANSAS CITY NOV 5 1911" The times are "7-PM" and "8-PM" Mailed and sent to the same post office. It's addressed to "Mr Raymon Walker, MC book" No street address or city name, so it might have gone to a box in the building, or it was for counter pick up, or the mail man knew everyone on his route. And the message, "Mr. Walker, Dear friend thank you verry much for your remembrance towards me. Will leave KC November the 6th for Va by the way of Atlanta, Georgia. Your G. McWilliams" Mr Walker, Dear friend, a strange mixture of the formal and familiar. And he misspelled dear friend's first name. Very strange.
