In América Tropical: Oprimida y Destrozada por los Imperialismos, how is the abstract discussed?
América Tropical is a 98-foot wide fresco mural created in 1932 by David Alfaro Siqueiros and other artists in Los Angeles, California, on a second-level exterior wall of the Italian Hall.  It was painted over soon after its completion on an external wall of the Italian Hall on Olvera Street, in El Pueblo de Los Angeles Historical Monument of Downtown Los Angeles.  It was restored and revealed to the public in 2012, 80 years to the day after its first unveiling.
