The National Museum of the Salce Collection preserves the largest collection of advertising graphics in Italy donated to the Italian State by Ferdinando Salce (1877-1962), known as Nando, from Treviso, with a will dated 26 April 1962. The accountant Salce developed an irrepressible passion from an early age for the illustrated posters and thanks to the wealthy economic condition of the family he dedicated himself to collecting almost exclusively. In 1895, at the age of just 18, he bought the Auer patent gas incandescence by Giovanni Maria Mataloni, the first poster in his collection. Since then he will never stop: in the course of his life he will collect about 25,000 pieces, kept until his death in the attic of his house in Piazza Mazzini, in the historic center of Treviso.

For decades the Collection did not benefit from its own exhibition space and its knowledge remained entrusted to temporary exhibition events.

In 2014 it became a permanent museum, based in San Gaetano and accessible to the public since May 2017. In 2021, the exhibition and conservation site of Santa Margherita was added, also in Treviso, in via Reggimento Italia Libera. The Museum therefore has two locations, both in the historic center of the city, a short distance from each other. The museum offer in both locations does not have a permanent configuration: for scientific choice and for conservation reasons, the materials of the Salce Collection are exhibited in rotation in the context of temporary exhibitions of a monographic or thematic nature.

The San Gaetano museum is spread over four floors which house service spaces (reception, bookshop, infopoint, toilets) and display surfaces specially designed for graphic materials. When entering the museum, it is also possible to visit the church of San Gaetano, a building of the Knights Templar, rich in history and works of art.
