Cortesí project was selected as one of six winning posters out of 150 entries from six continents.

Winners were announced last week. Designers were required to call attention to an important international issue using a unique design concept.

Cortes chose child prostitution, using hand-sketched drawings of old-fashioned paper dolls to make her point. "Child prostitution is a global issue," said Cortes. "Paper dolls are something that girls from all around the world have played with. I wanted to use the image to shock people into paying attention."
