Rafael Coutinho is actually son of the famous cartoonist Laerte, but he got his own career and fame in visual arts before he made this first project adapting his mother's comics.
The colorist for that project, Priscilla Davanzo, went to university with Rafael Coutinho and besides of a friendship, she's posed for him (paintings, drawings and even sculpture) in several occasions. As a matter of fact until now, every time she visits Sao Paulo she poses at his creative drawing classes.
