Che's picture, not Che, is the hero. Everyone recognizes it, just as everyone recognizes the Coca-Cola logo and the Mercedes Star.
When I visited Loja, Ecuador on a double-decker bus tour which was especially exciting because the guide tooted an airhorn when low-flung electrical wires were strung across the street, and we all had to duck to avoid electrocution, we visited the provincial University there. In the center of the campus, there was a very nice tower, and on two buildings on either side, the usual campus revolutionaries had painted four figures: Che, Fidel, Marx and Engels. At the time, I did not recognize Engels and asked the university person who the fourth figure was. No one could name who it was. Someone helpfully remarked that it was not Chairman Mao.
La Universidad de Loja has a very pleasant campus.
The one figure everyone recognized was Che. I think it is safe to say that he is the revolutionary with the best fashion sense (berets are classy, baseball caps and even Fidel's squared off cap are not), as well as easily the most photogenic.
Runners up would surely be Emiliano Zapata, Pancho Villa, Nikolai Lenin, and Chairman Mao, with honorable mention for Mustapha Kemal Ataturk and Theodore Roosevelt.
Chairman Mao ironically is one every bill of the Chinese currency, even as the leaders of the PRC ignore his Great Leaps and Cultural Revolution entirely.
