The Felipe Préstamo collection consists of 75 slides of Cuba, including the slides of the following seven villages founded by Diego Velázquez de Cuellar: Havana, Baracoa, Bayamo, Santiago de Cuba, Sancti Spiritu, Puerto Principe and Trinidad, which were taken from the photographs and postcards held in Cuban Heritage Collection.

The Guillermo González collection contains materials documenting the engineering career and personal life of Cuban engineer Guillermo González (1932-2013), including slides, photographs and images, memorabilia, personal papers, and audiovisual materials.

These materials include slide collections, photographs, postcards, advertisements, tourist brochures, and ceramic plates from famous Cuban locales. The collection also contains materials documenting González's career as an engineer, such as awards, engineering essays, and blueprints, most from his time in Miami, but some materials do date from his time in Cuba. While most of this collection’s slides, photographs, audiovisual materials, and memorabilia document life in Cuba, the personal papers document González’s life in both Cuba and in Miami. Other materials include play scripts and videotapes on subjects that were of personal interest to González.

González's extensive collection of slides have been maintained in the original order that they were created. Most of the slides are organized into slide books and each binder is further divided into thematic tabs, which are identified in the container list in this finding aid. A small amount of slides were in slide projector decks, which have been kept together in folders accompanied by the slideshow notes. Box 10 contains photographic prints from slide negatives that González donated to the Cuban Heritage Collection previously.
