Veronica Lawlor made this nice book about Reportage and documentary drawing, Tips and techniques for Drawing on Location.
And I am proud to say that one of my sketches features in it, a 2011 action sketch of cowrunning. I think it was the last time our group joined the local Carnaval-Koerennen games. Anyway, like every year I managed to make this little sketch.
The book is very nice, with a lot of different artists collaborating. Even though the illustrations are sometimes rather small, it's still a treasure of ideas.
