Americana

Americana refers to artifacts, or a collection of artifacts, related to the history, geography, folklore and cultural heritage of the United States. Many kinds of material fall within the definition of Americana: paintings, prints and drawings; license plates or entire vehicles, household objects, tools and weapons; flags, plaques and statues, and so on.

Patriotism and nostalgia play a defining role in the subject. The things involved need not be old, but need to have the appropriate associations. The term may be used to describe the theme of a museum or collection, or of goods for sale. via Wikipedia
