On 28 September 2020, Spain’s postal service officially issued a stamp with an image of the Wanda Metropolitan stadium, home to the Atlético de Madrid football club and a work of Cruz y Ortiz Arquitectos.

The second stamp of the series went into circulation on 10 November 2020, in advance of the 2021 commemoration of the 80th anniversary of Madrid’s Zarzuela Hippodrome, the horse racing course designed by the architects Carlos Arniches and Martín Domínguez with the engineer Eduardo Torroja. The construction is printed on a diptych-shaped sheet from which the roof and stands rise in a 3D effect, as in pop-up book. The picture shows an instant during a horse race.

The third of the series came out this past 31 March 2021, this time highlighting the Botín Centre in Santander, a work of Renzo Piano in collaboration with Luis Vidal.
