HONG KONG — Soon after a woman in Hong Kong was hit in the eye at a protest, her likeness began circulating as a meme on internet forums where many demonstrators blamed her injury on the police. Within a couple of weeks, protesters had raised over $25,000 online to build a 13-foot statue of her.

They called it Lady Liberty Hong Kong, a nod to the Statue of Liberty in New York City.

Street art and graphic design are defining features of the pro-democracy demonstrations that have roiled the semiautonomous Chinese territory since June. Artists often work quickly and anonymously, and present their oeuvres either in Reddit-like internet forums or public places with heavy foot traffic.

Much of the art channels pop-cultural aesthetics taken from Marvel Comics and Japanese anime. And in a financial hub where legions of young people are glued to Instagram, even the street art seems designed to go viral online.

Some protest artworks depict the movement’s heroes — including Lady Liberty Hong Kong and a demonstrator in a yellow raincoat who fell from a building in June — in somber, reverential terms. Others are whimsical sendups of Chinese officials, including Carrie Lam, the city’s embattled leader.
