Summary  
This document is an FBI record from August 4, 1961, related to Santiago Alvarez Rodriguez, a Cuban revolutionary associated with anti-Fidel Castro activities. It notes that the FBI closed its investigation into Alvarez due to his relative inactivity in Cuban revolutionary matters at the time. However, the CIA maintained operational interest in Alvarez and his son, though no further action was taken by the FBI unless renewed interest emerged. The document references a publication called "Esbrilos" (also spelled "Ebirros" or "Sebirros"), which was linked to anti-CASTRO activities and had limited distribution. It mentions that the paper was last printed in December 1960 and not believed to have been published after December 1966. The text includes coded references to informants (e.g., MM T1-1, MM 726-S) and internal FBI/CIA communications about surveillance and operational interests.
