Lepage then imported the first French cinematographic equipment into the country. In 1897, using a Gaumont camera, Py (known as Eugenio Py in South America) subsequently shot what was for some time considered the first Argentine film, of the Flag of Argentina, La Bandera Argentina (nowadays it's known that a German named Federico Figner screened three short views of the city of Buenos Aires before Py's). Py continued to produce films for exhibition at the Casa Lepage for several years, working as part of the cross-national film production, distribution and exhibition system developed by Glücksmann in Argentina, Uruguay and Chile.
Py's early films included Visita del Dr Campos Salles a Buenos Aires (1900) (the first Argentine documentary, and La Revista de la Escuadra Argentina and Visita del general Mitre al Museo Históric (1901). Py introduced the concept of recording history in the making in Argentina, by filming the arrival of the Brazilian president at the time accompanied by the Argentine president, and filming Alberto Santos-Dumont during a small recording that went on to capture what is probably the first "gag" in the country's history (a third man kept standing between Py and Dumont, interrupting the film, until he received a spit in the face, upon which recording finished).
