We can thank the Brits for introducing us to the world of pop art, the bright and colorful artistic movement that came about in the mid 1950s in England. The United States jumped on the wagon a few years later, giving us Andy Warhol, Roy Lichtenstein and Jasper Johns in the 1960s. Now included in that mashup is Romero Britto, a Brazilian born, self-taught artist who took the art scene by storm. Britto will be bringing his extraordinary collection to Northport’s LaMantia Gallery from July 15 through 23, showing guests his life in vivid color.
