Child labour, modern slavery, fair and equal work opportunities were the themes explored in this year's contest.

Poster for Tomorrow was formed in 2009 in Paris by a group of artists encouraging people, both in and outside the design community, to create posters which would stimulate debate on human rights issues.The theme for this year’s competition was the universal right to fair employment with exhibitions held across the globe in 30 countries.

The 22-year-old Nisar, who is a second-year Visual Arts student at Karachi University, was moved by the plight of the children working in the torturous brick kiln factories in Pakistan and aimed to show the two different worlds that exist in the country.

"My poster is a super imposition of two children — both having very different futures. Some children do get a chance to have a secure childhood while others do not get the care, comfort and security that they deserve. This variation is not just class-based, it happens amongst privileged children as well, many do not get the childhood that they deserve," Sara, who made it to the top 100 on her first attempt, says.

Sara has an interest in using art as a medium for social activism and she believes that for a country like Pakistan, which has a low literacy rate, design is a medium to reach out to everyone.

"Design is a way for me to talk to people; to fulfill a social cause that is so close to me."

The purpose of this year's theme was to make raise awareness about the rights of workers; from the small boy working in a sweatshop to the woman being paid less than her male colleagues or the physically challenged man denied an office job because of his wheelchair.

In Pakistan, the exhibition featuring the top 100 posters was held at the Arts Council, Karachi on Friday.
