Colombian artist Pedro Alcántara informs Puerto Rican artist Lorenzo Homar that the studio at the Museo [La Tertulia] no longer exists, and therefore its collective, the Taller Gráfico [Graphic Workshop], is operating on the basis of “ongoing projects, persistence, discipline, and faith.” Indeed, its functioning is possible thanks to the Party, which supported its work by allocating funds to make a portfolio with texts by Gabriel García Márquez and Álvaro Medina, and thirty-two graphic works by Colombian artists from the time of independence until the present. This has made the continued existence and development of the Graphic Workshop possible while providing the Party with a source of funding for the revolutionary struggle. Alcántara believes that this portfolio will rescue figures in the history of Colombian graphic art from oblivion, artists that have been neglected by art critics including, for instance, the artists Marta Traba mentioned as having been previously ignored. One example is master printmaker Luis Ángel Rengifo who organized the Escuela de Grabado [Printmaking School] in Bogotá.

Lorenzo Homar (San Juan, 1913-2004) organized in 1957 the Taller de Gráfica [Graphics Workshop] at the Instituto de Cultura Puertorriqueña, which he directed until his resignation in 1973. Some of the foremost artists of Puerto Rican art studied printmaking techniques in this workshop. Homar inspired in them dedication and love for the art, for, as he once said: “There is no vocation without discipline, and without discipline there can be no freedom in art, or elsewhere.” Homar was one of the organizers of the First Bienal de San Juan del Grabado Latinoamericano held in 1970. He developed the technique of silkscreen and offered numerous workshops in and outside Puerto Rico.   Homar met Colombian artist Pedro Alcántara (b. 1942) when the latter was in San Juan for an exhibition of his work at the Galería El Morro (Dibujos y monotipos [Drawings and Monotypes], December 4, 1970) and for the Primera Bienal de San Juan del Grabado Latinoamericano [First Latin American Print Biennial, San Juan] (1970) in which Alcántara participated. Later, Alcántara had the opportunity to work in Homar’s studio, where he first came into contact with the silkscreen technique. From that time on, they became and remained close friends. In 1972, Homar was invited by the Museo La Tertulia in Cali, Colombia, to give a class on silkscreen [printing] to a group of artists from that city. During the ten-day workshop, artists Pedro Alcántara, Enrique Grau, and Phanor León were able to print silkscreens for the portfolio that Cartón de Colombia was putting together that year. Shortly after the workshop, Alcántara, with Homar’s assistance, began working on plans to open a permanent printmaking studio. On August 23, 1974, a show featuring some of Alcántara’s graphic work from 1964 to 1974 was held at the Museo de Grabado Latinoamericano [Latin American Print Museum] of the Instituto de Cultura Puertorriqueña. Homar designed and printed the poster announcing the exhibition.
