1962-63 Tulia I by Tulio Crespi from Argentine.
I'm impressed. That wasn't easy to find - well done and a point to you.
I've a hunch the car was powered by a locally-built Renault engine, like other Crespi cars, but I don't know whether it was built to an FIA-designated formula.
PS the caption suggests this was the first monocoque racing car, which is highly hopeful, and would be news to many earlier car designers.
