The 'José Luis Guerra Aguiar' Cuban Postal Museum, a unique institution in Cuba, joins the celebrations for the 500th anniversary of the foundation of the village of San Cristóbal de La Habana with an interesting and well documented transitory exhibition.

From its vast postal and philatelic patrimony the Museum has selected in this special opportunity the emission 'Old Havana: Patrimony of the Humanity'. It started circulating on November 25, 1985, made up by five values designed by José Antonio Medina, which show scenes of the Old Square; the Castle of the Royal Force; the Cathedral of Havana; the Palace of the General Captains; and the Small Temple.

Visitors will be able to appreciate the designs approved for such a significant issue, as well as the stamps (their facial values are 2, 5, 20, 30 and 50 cents) much sought after by national and international collectors, as well as the first-day envelopes already circulated.

In the cache of the first-day envelopes, we can see the coat of arms of the city of Havana, the UNESCO logo and a sepia-colored image of fragments of the ancient wall that surrounded the village of Havana during the colonial period.

The conservation projects undertaken in the so-called Wonder City made it possible for the Historic Center of Old Havana and its system of colonial fortifications to be included on the World Heritage List on December 14, 1982, approved during the Sixth Session of the Intergovernmental Committee of the World Cultural and Natural Heritage Convention of the United Nations Educational, Scientific and Cultural Organization (UNESCO), in the city of Paris, France.

In philatelic language, a design stamped on an envelope or card by means of a metal stamp or rubber stamp and bearing inscriptions and/or illustrations is referred to as a cache. They describe or commemorate events, such as the anniversary of an institution, the tribute to a famous person, the first day of issuing a stamp, a first flight, a philatelic exhibition, etc.

The 'José Luis Guerra Aguiar' Cuban Postal Museum, located on the ground floor of the Ministry of Communications in Havana, near the Revolution Square, is open to the public Monday through Friday from 8.30 a.m. to 4.30 p.m.
