Could anyone help me with why this cover would have been opened by the War Office Postal Censor and due to my not knowing very much about the War Office Postal Censor what was it? Also, can anyone tell me about the Censor 4858 label.
I have seen examples of 2 covers from the Anglo Russian Hospital in Petrograd sent via London to Canada and the two I have seen in the Maple Leaves journal are not censored but do have Russian Red Cross Anglo-Russian Hospital. Petrograd cachet.
Thanks in advance
