We won’t often do this for an office building, but here’s an abridged Wikipedia entry describing it:  “Edificio Carrión or Edificio Capitol is an outstanding example of the expressionist-leaning trend within the wider scope of rationalist architecture in Spain, an icon of both the Gran Vía and the city.  54 metres high, the building lies on the corner where the Gran Vía meets the Calle de Jacometrezo. The project was entrusted to Vicente Eced Eced and Luis Martínez Feduchi, who were influenced by the November Group.  Building works started on 11 April 1931.  The building was inaugurated on 15 October 1933.  Depicted in many artistic works, the building’s façade was prominently used as setting of the movie El día de la bestia.  The building was declared Bien de Interés Cultural in 2018.”  And the postcard?  Stamped and mailed in 2024, but no cancellation.  Grade: 3
