With Tango there are three

"Con Tango son tres" is the true story of a unique pair of chinstrap penguins that the keeper of the Central Park Zoo in New York, Rob Gramzay, gave them the opportunity -by depositing an egg in their nest- to have a brood after observing that they unsuccessfully incubated a stone. Thus was born Tango, who was the first penguin to have two parents. Justin Richardson and Peter Parnell's first children's book was a hit and, since its publication in 2005, has received numerous awards. Although it has also been censored by conservative sectors, contrary to the new family models. Author: Richardson, Justin;Parnell, Peter | Illustrator: Cole, Henry
