Homar was also the designer of the logo of the Instituto de Cultura Puertorriqueña (Institute of Puerto Rican Culture).

Lorenzo Homar was born in 1913 in Barrio Puerta de Tierra in San Juan, Puerto Rico.

Although he attended grammar school in San Juan, in 1928 due to financial difficulties, his family is forced to move to New York City.

Furthermore, the income from his position at Cartier allowed Homar to take night classes in painting, design and typography at Pratt Institute.

Homar then served in an Army Intelligence Unit where he learned cartography while working for the Second Amphibious Combat Engineers Brigade.
