The Matthew Marks Gallery is sponsoring a limited-edition sale of 20 portraits of world leaders by Platon, staff photographer at The New Yorker and contributor of iconic covers to Time Magazine and other publications around the globe.

On September 15 from 6:30 to 8:30 p.m, Platon and Carroll Bogert, deputy director of Human Rights Watch for external relations, will present the work with a lecture on their collaboration at Matthew Marks Gallery, introduced by The New Yorker editor David Remnick.

Platon and Human Rights Watch have worked in partnership on groundbreaking projects to celebrate human rights activists around the world, including portraits of Burmese monks and Egyptian protest leaders. The portfolios have been published in The New Yorker and dozens of media outlets worldwide.

The 20 images to be sold are drawn from Power, Platon's new book published this year by Chronicle Books featuring more than 100 portraits of world leaders. They include Barack Obama, Mahmoud Ahmadinejad, Tony Blair, Robert Mugabe, and Silvio Berlusconi, as well as one man apparently out of power – Muammar Gaddafi.

These portraits are of leaders who, for better or worse, have been influential in their own countries and the world at large. Some have promoted human rights values and some have undermined them; quite a few have done both. The proceeds from the sale will help Human Rights Watch take on those who abuse human rights around the globe, including some of those whose portraits are being sold.

Human Rights Watch said the partnership with a portraitist of Platon's caliber enables the organization to tell human rights stories in a fresh and vivid way through elite global media, using high-quality, high-impact content.

"Platon opens new doors for Human Rights Watch in media all over the world,” Bogert said. "The beauty of his imagery gives us a new way to communicate our work that transcends language and culture."

Platon received the highest security clearance at the United Nations to create intimate, close-up photographs of the world's leaders as they stepped off the podium after addressing the UN General Assembly.

In his introduction to Power, David Remnick described Platon’s special talent: “He is far more than a technician with a knack for access. He does constant battle with the subject’s practiced capacity to evade a penetrating eye. More often than not, victory is his.”

Matthew Marks Gallery, 523 West 24^th Street, NY, NY, will exhibit the 20 images from September 15-17. The prints are also available online. The book,  Power: Portraits of World Leaders (Chronicle 2011) is also available online.
