In 1963, a group exhibition of Puerto Rican graphic art was organized under the title: Exposición Colectiva de Grabados Puertorriqueños: Pequeña Retrospectiva [Small Retrospective]. Regarding the exhibition, the Italian art buyer Luigi Marrozzini, based for some time in Puerto Rico, states that the main purpose of the Galería Colibrí is the exhibition and sale of prints. Marrozini explains that the reason for calling the exhibition “small” is that the show has no intention of being a comprehensive retrospective. On the contrary, the work is presented in order to showcase the high quality achieved by printmaking on the island. The writer points out that there has been a resurgence of traditional printmaking, not just in Puerto Rico, but worldwide. In 1963, the popular interest in this work was unprecedented.

The artists who showed their work at the Exposición Colectiva de Grabados Puertorriqueños: Pequeña Retrospectiva, held from September 6 to 30, 1963, at the Galería Colibrí were: José R. Alicea, Myrna Báez, John Balossi, Isabel Bernal, Luis G. Cajiga, John Dixon, José Manuel Figueroa, Domingo García, A.E. Gumbs, Luis Hernández Cruz, Manuel Hernández Acevedo, Lorenzo Homar, José M. Iranzo, Epifanio Irizarry, Rafael López del Campo, Antonio Maldonado, Carlos Marichal, Augusto Marín, Antonio Martorell, Carlos Osorio, Mela Pons de Alegría, Richard Pritts, Bonnie Reissman, Carlos Raquel Rivera, Rafael Rivera Rosa, José Rosa, Luis Santos, José Antonio Torres Martinó, and Rafael Tufiño. The exhibition included 100 prints. Homar himself designed the logo for the Galería Colibrí.The galleries that promoted graphic work by artists from Puerto Rico that opened in San Juan in the 1960s included Galería Isla (opened in 1963), Galería Sol (opened in 1964) and Galería Santiago (opened in 1965). Of them, the Galería Colibrí (opened in 1963) under the direction of Luigi Marrozzini (1933–1997) was particularly outstanding. It was sponsored by artists and by the Instituto de Cultura Puertorriqueña (ICP). In its first years, it focused solely on the exhibition and sale of graphic art from the island.
