A Mexican commemorative stamp marking the 155th anniversary of Progreso, Yucatán, depicts the port’s lighthouse and maritime setting. Diario de Yucatán’s 22 October report describes a printing of 300,000 stamps and a cancellation ceremony held on 30 June 2026 beside the monument to city founder Juan Miguel Castro Martín.

Mayor Erik Rihani González told the newspaper that contact with Correos de México developed through a façade-restoration programme that included the local postal building. A subsequent visit by postal director Violeta Abreu González helped lead to the stamp proposal in February.

The lighthouse was selected as a distinctive architectural and historical landmark. Municipal secretary José Efraín Escalante Domínguez said the council sought more stamps approximately two weeks after the ceremony but was told the available stock had been exhausted. This describes the council’s request, rather than proof of a nationwide sell-out.

The photographed presentation material shows the stamp alongside a commemorative first-day envelope and a technical information card. The envelope’s cancellation reads 30 June 2026, keeping the original release event distinct from the October newspaper coverage.
