Pratt taught drawing in the Escuela Panamericana de Arte directed by Enrique Lipszyc. He often travelled to South American destinations such as the Amazon and Mato Grosso. During that period he produced his first comic book as a complete author, both writing and illustrating Anna della jungla (Ann of the Jungle), which was followed by the similar Capitan Cormorant and Wheeling. The latter was completed after his return to Italy.
