Question: what is the significance of the black and white puerto rican flag?
Answer: Since at least 2016 an all-black rendition of the flag of Puerto Rico has been a symbol of Puerto Rican independence, resistance, and civil disobedience. A door at 55 Calle San José, painted with a mural depicting the traditional red, white, and blue Puerto Rican flag, had become a familiar image of Old San Juan.
