Document 3: Flag of Puerto Rico: In a letter written by Maria Manuela (Mima) Besosa, the daughter of the Puerto Rican Revolutionary Committee member Manuel Besosa, she stated that she sewed the flag. This created a belief that her father could have been its designer. In her letter she described the flag as one which consists of five stripes that alternate from red to white. Three of the stripes are red, and the other two are white. To the left of the flag is a light blue triangle that houses one white five - pointed star. Each part of this flag has its own meaning. The three red stripes represent the blood from the brave warriors. The two white stripes represent the victory and peace that they would have after gaining independence. The white star represented the island of Puerto Rico. The blue represents the sky and blue coastal waters. The triangle represents the three branches of government. Finally, it is also believed by some that it was Lola Rodríguez de Tió who suggested that Puerto Ricans use the Cuban flag with its colors reversed as the model for their own standard. The color of the Cuban flag's blue stripes, however, were a darker shade of blue, according to Professor Martí.
