The collection of 15 Correos uniforms illustrates the evolution of postal attire throughout the 19th and 20th centuries. The postillion's uniform stands out for its flamboyance and its original metal horn. Also significant are the urban postman's uniform from 1856 (the oldest one in existence); the dress uniform of the chief administrator of Correos from 1906, worn at solemn events; the 1976 brown woollen travelling uniform used for working on postal trains; the sorting and delivery uniform from 1992 designed by Manuel Piña; and lastly, the current male and female delivery uniforms, designed for functionality, with a delivery cart in keeping with the needs of today.
The hall features two oil paintings of postal workers. The first is a large-format work by Calderón entitled Cartero Urbano or "Urban Postman," in which a uniformed postman from the 1950s is about to set out to deliver the post. The second painting is a naive piece by Elena Ciordia depicting a group of letter carriers in the 1980s. Another interesting exhibit is a bicycle from 1930 with a Correos plate, used for delivering the post.
