These world travelers weigh about a ton each and never utter a word.
Cruise passengers visiting on a port-of-call stop through mid-April will have an opportunity to see Mexican artist Rivelino's sculptures that make a statement about self-censorship and freedom of expression.
Passengers who explore on foot will easily find the 11 1/2-foot-tall figures whose mouths are covered up with plates. The artwork has been on display in many countries, including Portugal, Spain, Italy, Germany and his home country of Mexico.
For visually impaired people, the sculptures are accompanied by an iron Braille box with small-scale pieces inside that people can touch to experience the work.
Rivelino, whose full name is José Rivelino Moreno Valle, spoke at the Jan. 29 debut of "Our Silences" in San Diego.
