The museum is in Cuajinicuilapa, Guerrero, not Mexico City. The federal cultural information system identifies a local museum committee as its operating body and describes a collection using photographs, maps, models, costumes, masks and musical instruments. Those materials tell a regional story, not a complete account of every Afro-Mexican community.
Afromestizo appears in the institution's formal name and in earlier scholarship and cultural policy. Retaining that name identifies the museum accurately; it does not prescribe how a person must describe themselves. In conversation, use the person's own terms rather than assigning an identity from appearance, a museum label or an assumption about ancestry.
The distinction matters because recognition is not merely a matter of adding an African influence to an otherwise finished national story. A community museum can also ask who has been allowed to tell that story, whose knowledge has been collected, and who controls its interpretation.
