This was a pretty gigantic piece of "doodle artwork" (meant to look like the kind of thing you'd scribble on a notepad whilst you're on the phone).
A whole piece designed to have 6 segments covering differing aspects of finance.
Hovering over the thumbnail below will show better detail...
The illustrations were used in targetted mail, posters, and can be seen in the background of their website: http://www.financenow.co.nz/
And, though the illos appear sketchy in nature, they are actually vector illustrations, scalable to any dimension.
