The Society of Illustrators has awarded ProPublica a silver medal in the organization’s annual competition, which recognizes top achievements within the field of illustration. Artist Matt Rota was honored in the editorial category for his illustrations featured in the ProPublica investigation Firestone and the Warlord.

Under the direction of ProPublica design director David Sleight, Rota’s vivid artwork breathed life into scenes from the story of the American tire company’s relationship with Liberian warlord Charles Taylor, as it continued managing its rubber plantation during a vicious civil war.

Award winners were selected by a prestigious jury of renowned illustrators, art directors and designers, who reviewed thousands of entries from around the world. Rota’s original illustrations, along with the work of other winners, will be on display from Feb. 3-27 at the Museum of American Illustration. Read more about the Society of Illustrators’ award here.
