This collection deals almost exclusively with advertising, spanning the design process from layouts and proofs to finished brochures and magazine advertisements. The majority of the brochures are for hotels in Florida (particularly on Miami Beach) and in the Caribbean and South American (most notably for the Intercontinental chain). Other ads relate to local businesses, including banks, electronic firms and travel companies. Public sector advertisements were commissioned by the Florida Department of Commerce (including the Divisions of Tourism and Economic Development) and the City of Miami Department of Publicity and Tourism. Finally, to a lesser extent there is information on the proposed Interama complex, the Greater Miami Opera Guild and southern Florida commerce and development (such as the Miami Beach Convention Center, Dade County Port Authority, Orlando International Free Zone). A few of the brochures are in Spanish.
