This poster won the Viridian design competition for a poster to warn about the dangers of heatstroke caused by greenhouse weather. The poster needed to be wordless (or almost so), and embody something of the Viridian principles of design. For this design I wanted to restrict the printing to 3 colours, one of which is a flat background, so it could be silkscreened or even stencilled (all except for the windows on the little factories).
