Miami may be renowned for its nightlife, beaches and other trivial things, but we also are the venue for one of the country’s biggest book fairs 30 years standing. Miami Book Fair International unveils its official 2013 posters at 5 p.m. today in the Mural Room of the historic Freedom Tower at Miami Dade College (600 Biscayne Blvd., Miami). The event, held as part of the launch of MDC’s culture campaign, ACTIVATE: MDCulture, and the city’s DWNTWN Arts Days, will include plenty of literary flourishes like impromptu poems courtesy of Poem Depot as well as musical and theatrical performances. One of the two official Book Fair poster artists, Francisco Capdevila is one of Spain’s most important illustrators and comics artists, a nod to the 500th anniversary of Ponce de Leon’s arrival in Florida . The second official poster created by Paul Pope is dedicated to Generation Genius Days, the component of the Fair that is all about kids and young adults.
