Caption (my translation):
Here we see the American singer in Havana together with his wife Maria. Dance couple Ana Gloria and Rolando join them in the photograph. Behind them is the Cubana de Aviacion airplane that offered the Tropicana Special roundtrip flight between Miami and Havana. For $68.80, tourists could enjoy a roundtrip flight, which included an actual show on the plane with Ana Gloria and Rolando, a night at the Tropicana Cabaret with food and drinks, and a stay at a hotel in Havana.
