::: POSTAL STATIONERY - Comparison of Knives P-10 & P-11 :::

Back to Postal Stationery.


Knives P-10 (lower envelope) and P-11 (upper envelope) compared. The rounded flap of knife P-10, used in the earlier printings of the 1¢ and 2¢ values contrasts with the pointed flap of P-11, used in printings to fulfill the order of January, 1889, and all subsequent orders for these two values. Notice also the difference in the corner angles where the flap meets the body of the envelope. Knife P-11 has a wider angle.
