The Casals/Homar Portfolio brings together the artistry of three great masters:
Score by Don Pablo Casals,
Verses by Don Tomás Blanco
Serigraphs designed by Lorenzo Homar.

Commissioned by Galería Colibrí Director Luigi Marrozzini, it was printed at the Taller de Artes Gráficas of the Institute of Puerto Rican Culture and published in 1970 in an edition of 150, signed and numbered by the three masters, on Arches paper as follows: from 1 to 100 in Arabic numerals; 20 from I to XX in Roman numerals; 20 H.C. reserved for collaborators and 10 artist proofs.

Each portfolio contained an additional series of the four landscapes printed on Rives BFK paper.
