Acosta Collection contains parts and scores for arrangements by the Cuban composer Rodrigo Prats, written between 1956 and 1960.  Acosta and Prats collaborated on a series of dance performances called "Ballet Español", which included works of Ernesto Lecuona and Agustín Lara, among others, when they both worked for the Sylvia M. Goudie dance studio in Havana.
