El Muchacho is the Cuban release title of a Japanese movie called  "Shonen", or "Boy" as it was released in English speaking countries.

The tale is based on a true story of a family of Japanese con-men and woman, who were, of course, thoroughly reprehensible, although there is a degree of reluctant admiration for their dedication. More here: http://www.imdb.com/title/tt0063876/?ref_=fn_tt_tt_1

This poster is a rare bird indeed, being the only Cuban currently in the Drivepast collection, the only silk screen in the collection, and having the only Triumph Spitfire in the collection.
