The War Horse

This project is the brainchild of our Graphics Editor Bonnie Berkowitz who, some three weeks ago, saw the potential for a big piece for our Sunday Arts section.

War Horse, the Tony Award winner play based on Michael Morpurgo's novel was coming to the Kennedy Center on October 23 and the fact that the main character of the show was a life-size puppet created by the Handspring Puppet Company of South Africa, seemed like a great opportunity to create an explanatory infographic for our readers.

Final double page

Given the bizarre and unconventional appearance of the puppet, I decided to start working first on the cover illustration for the section so I could familiarize myself with the creature. I used ink pens of different widths for the outlines and then applied washes of watercolour.

The overal design of the infographic had the usual central theme which I planned to use as a visual guide to explain how then puppet was operated and as a map for a series of diagrams pointing to some crucial mechanical components of the horse. The graphic also would include two secondary components: a description of several configurations of the puppet and a timeline, discussing the evolution of several puppets created by Handspring that, ultimately, inspired the creation of Joey.

Production sketch

The main component of the graphic was created on a 20 x 25 in rigid board with the same technique than the cover Illustration.

At this point, I also decided to give the graphic certain appearance of age, by creating a background  imitating a worn off fabric texture. The idea was originated by the fact that the War Horse puppet exterior is made of cane and cloth.

In order to keep a stylistic coherence acros the whole piece, I decided to go for a hand-drawn feel for the whole graphic.


That was also the case for all the secondary illustrations.
