Los tramposos ("The cheaters") is a 1959 Spanish comedy film directed by Pedro Lazaga and starring Tony Leblanc and Antonio Ozores.
Two small-time con men make a living of swindling people.
They have a relatively happy life despite some "visits" to Carabanchel Prison.
Having failed in other jobs, open their own travel agency, which turns out to be a success after some comical incidents.
Spanish critic Carlos Aguilar in his Guía del cine español considers this film "in his own way, a classic".
