A notable Mexican Philatelist

José Lorenzo Cossío y Cosío (1902-1975) was a passionate philatelist for fifty years. He authored philatelic works such as México Emisión Postal 1874-1883, and La falsificación de algunos timbres postales antiguos de México, both published in 1932; Los timbres mexicanos de ocho reales de 1861, negro y café con sobre-carga “APAM”, in 1935; Los timbres de tres centavos del Imperio de Maximiliano and the Álbum postal instructivo de la República Mexicana, in 1936; México primera emisión postal para el exterior, in 1937; México álbum postal histórico, in 1956 and Sellos usados en las oficinas del correo de la República Mexicana durante los años de 1868 a 1879, in 1961, among other research he performed.

Don Lorenzo collected a documentary archive on philately of approximately 6 thousand volumes; the Cossío Fonds is a vast collection consisting mainly of catalogues, albums, bulletins, magazines and other publications from five continents. This important philatelic collection includes copies dated after the first issue of stamps in Mexico, in 1856, covering a period until 1974.

Your presence keeps the MUFI Library alive, and with your donation you can contribute to the purchase of new copies; the José Lorenzo Cossío y Cosío Library is updated continuously and already represents a historical and cultural heritage of Mexico. Come and see for yourself!

Genuine or false?

To determine the legitimacy or falsification of postal stamps, studies in forensic document examination and technical and scientific procedures are needed to know if the ink used existed at the period of the emission or if the overprints and cancellations effectively correspond to their periods. Vain perhaps, but it is fascinating to learn about the dyes that have been used in the manufacture of stamps as well as about adhesives. Discover the dossier on forgeries José Lorenzo Cossío prepared with the support of the Bureau de Peritajes (Expert Bureau).

And we have surprises for the kids too….

One day little Tara and her mother went to the Museum of Philately, visited the philatelic vault and were much surprised when they saw the first stamp of the world, the Penny Black. Tara’s mother recalled that her father had given her a box with a letter and a stamp collection before he died. In the letter her father said, that he had not been able to arrange his collection and that his last wish was for her to do so. While this memory floated in space, Tara continued to explore and found herself in front of a new universe of books. She thought that among so many books she would not be able to find a story for herself. Then a colorful book on a table called her attention. Magic captivated her and when she opened it, she was surprised, since in spite of being written in a strange language – stamps, timpres, estampillas, stempel- whatever, that she could read it! Tara understood that we communicate through letters and that many years later, this letter, and the envelope with its stamp becomes a pleasant memory, like the one that her mother just had. Grasp the magic of philately through our collection of works for children, specially translated for you. Read, learn and have fun playing with the applications on our tablet!

We thank collectors and philatelists for rescuing and preserving the practice of sending letters and post stamps and thus the post stamp. The MUFI is committed to safeguard the philatelic memory at the José Lorenzo Cossío y Cosío Library.
