Surface and airpost stationeries of Liberia

Between 1882 and 1920 Liberia made available the following categories of postal stationery for surface mail: envelopes, newspaper wrappers, letter sheets, post cards, post reply cards, and registered envelopes. From 1948 on, Liberia has issued two categories of airpost stationery: air envelopes and air letter sheets (aerogrammes).
