Campaigning work
Yet as much as Mauricio has focused on his finances, he has also been honoured for his efforts to use his cartoons - which include no less than 200 different characters - to promote good causes.
Themes he has promoted include protecting the rainforests, anti-smoking, vaccinations, the need for clean water, tackling pollution, and fighting drugs.
This work has seen him receive an award from the Pan American Health Organization, the public health agency that operates in all 35 nations across North and South America.
Mauricio is also the holder of a Brazilian presidential medal of honour, and his Monica cartoon character was named a United Nations International Children's Emergency Fund (Unicef) ambassador in 2007.
