If you have visited Coral Gables recently, you may have seen the large black-and-white photographs displayed in empty storefronts. All of the subjects, from postal workers to politicians and chefs to booksellers, are exhibiting the universal gesture for quiet. The 75 people in the photos represent the diverse community of Coral Gables and their portraits are the work of Miami photographer and dermatologist Flor Mayoral who started the “Silence Project” 12 years ago.
