Here is his description of the contents:
This is the entire Federal district of Buenos Aires with complete highway system, the main roads (with minor corrections from the previous “buenos aires main roads) and all of the remainding roads in the city. This file includes a large 3d portion of the downtown area and main buildings in Buenos aires. It also includes the entire subway system of buenos aires (current subway plus future plans and building of subway). This also includes the division of neiborhoods in Buenos aires.
