Alfredo Ortega and Sons was located at 13 Cinco de Mayo,  Mexico city  and appeared in the advertising section of travel books from the 1930s into the 1970s. The work of Ortega was European or colonial in style. A catalogue of the exhibit of Mexican Gold and Silver Craftsmanship held by the Museum of Popular Arts and Industries in 1952, confirms that the Ortega house was a  major manufacturer.
