Other collections include works from the Río de la Plata basin, Jesuit and Quito iconography, Brazilian furniture, and decorative arts from both colonial Latin America and Spain.

Among the museum's peculiarities is a collection of hand fans, tortoiseshell or horn ornamental combs used by women during the days of the Viceroyalty of the Río de la Plata and of the subsequent Argentine Confederation (in the first half of the 19th century).

Fernández Blanco sold the property and museum to the City of Buenos Aires the following year, however, and on May 25, 1922, it was re-inaugurated as the Museo de Arte Colonial.

His son-in-law and fellow connoisseur of Hispanic art, Dr. Alberto Gowland, continued to add to its collections, and in 1943, the city bequeathed to the museum an eclectic Baroque mansion acquired from Martín Noel seven years earlier.
