Street art legend Jorge Rodríguez-Gerada was recently invited to Amsterdam to create a huge land portrait spanning almost two football fields.

The gaze of an anonymous Mesoamerican human rights activist was etched into the ground to launch a campaign that aims to raise awareness of the plight of women who are illegally targeted and terrorised for defending human rights in that region.

It was commissioned by feminist foundation Mama Cash and created in one week with the help of 80 volunteers.

Rodríguez-Gerada – who was founder of the culture jamming movement in America – has made this kind of art before, creating a portrait of Barack Obama out of 650 metric tons of sand and gravel in 2008.
