I observed this cover on eBay, but can't understand the likely route that it took.
Mailed Delhi, India on Apr 9, 1895, then to London, England (date not legible), arrived Mexico City 18 May 1895. But how did it get into Mexico?
One possibility would be via USA and New York, then to Laredo, Texas, then Nuevo Laredo, and then on to Mexico City. There is a black "C" registration marking (#57369) from Nuevo Laredo, but no corresponding transit marking from New York or Laredo, and no US registry exchange label from Laredo, Tex.
An alternate route might be London to New York, and from New York by ship to Veracruz or other port, but there are no New York registry transit markings or a New York exchange label.
Another alternate route might be London to Vera Cruz, then Mexico City, but then why the Neuvo Laredo registration marking?
Was there some form of closed registered pouch service between London to Mexico via NY and Laredo where the letter would not be handled by the US postal authorities, but opened in Mexico?
So what am overlooking?
