Early papers of the 1P1Ex-SO

Here are additional examples of the three early papers for the 1P1Ex-SO.

Here is the 1E1, with a typically crisp impression.



The 1E2 stamp is very rare.



The 1E3 stamp shows some wear to the plates, especially the background.



Here are the watermarks side-by-side. From left to right: 1E1, 1E2, and 1E3.



The 1E4 is the most common of the four papers by a wide margin (my estimate is 10 to 1 where the 1 incorporates 1E1, 1E2, and 1E3 combined).
