Che was not in Cuba in 1955. He was in Mexico. He very well could have met Leonov in Mexico.
Che witnessed Operation PBSUCCESS and PBFORTUNE in Guatemala in 1954, which led him to the 26 July folks in Mexico.
Nice catch.
The point is, though, that short, blond, skinny, very thin-faced Nikolai Leonov turned both Raul and Che onto Soviet-style Communism, and a few years later, when he was a KGB colonel working as "Third Secretary" and "Assistant Cultural Attache" at the Soviet embassy in Mexico City, probably gave Sylvia Duran or Azcue some passport-sized photos of Oswald that had been taken in the USSR, and maybe even some forged-by-KGB Cuban visa application forms based on writing / printing samples from Oswald's letters, etc, and told Duran, Mirabal and Azcue what to do and say (all with Fidel Castro's blessings, one would think).
During his June, 1975, Church Committee testimony, Angleton tried to point out that Leonov's business card or calling card was found in Castro's notebook when he and Che, et al., were arrested in Mexico City in 1956.
