occasionally took group vacations, traveling en masse to other countries. Prohías took part in these vacations when possible, but as a Cuban exile, he had trouble gaining admission into some countries. At the airport before a Mad vacation to Italy, an airport official said, "You can leave if you want, but you can never come back." He later presented a drawing to MAD publisher William M. Gaines which showed himself being blocked by angry airport officials, letting his heart fly over their heads to the rest of the MAD gang. A note at the bottom translates to: "Mr. Gaines, my heart will always travel with you." Although he is most famous for Spy vs. Spy, the majority of his comic strips, such as El Hombre Siniestro, La Mujer Siniestra, and Tovarich, were published mostly or only in Cuba. Altogether, only about 20 of his roughly 270 contributions to Mad were of subjects and gags other than his spy series. One of those was the iconic cover image for issue #154 in 1972, depicting Alfred E. Neuman eating an ear of corn while leaving a single row of kernels unscathed due to the gap in his upper teeth. Most of the available information on Prohías's other work can be seen in the Spy Vs Spy Complete Casebook (Watson-Guptill, 2001) and the Spy vs. Spy Omnibus (DC Comics, 2011). He died of lung cancer at age of 77 and is buried in Woodlawn Park Cemetery and Mausoleum (now Caballero Rivero Woodlawn North Park Cemetery and Mausoleum) in Miami, Florida. Characters other than Spy vs. Spy El Hombre Siniestro: (The Sinister Man) wore a wide-brimmed hat and overcoat and had a long pointed nose, becoming the prototype for the Spies. His description from the Spy Vs Spy Complete Casebook says it best: "A dark and dastardly character, El Hombre Siniestro thought nothing of chopping the tails off of dogs, or even the legs off of little girls. . . [he] was born out of the national psychosis of the Cuban people." At the time right after Castro rose to power, there was a pronounced feeling of fatality and sinisterness in Cuba, and Prohías depicted this through his twisted El Hombre Siniestro strip. He and La Mujer Siniestra can be easily compared to the Spies—although, instead of fighting against a set rival, they simply do horrible things to anyone they can find. El Hombre
