Uruguay 1924 Official 'On Service' Birds Set

Uruguay · 1924 · 2 Centesimos to 2 Pesos

This is a complete set of eight official stamps from Uruguay, issued in 1924, featuring various bird designs. Each stamp is overprinted with 'OFICIAL' to denote its use for government correspondence.

Official stamps were issued by many countries for use by government departments, preventing the misuse of regular postage stamps and allowing for easier accounting of postal expenses. This set reflects Uruguay's administrative practices in the early 20th century.
