Something that I love about this piece is the use of vibrant inks and the format. This poster would be done on a budget, from the photographs the stock is fairly thin and looks no thicker than 80gsm. This makes for easy folding, and it holds the colours well.
The poster has similar aesthetics to blueprints. Thin, striking lines often complex in composition to demonstrate a plan in the field of architecture. The fold down format also benefits the print as it is more portable and can be handed out easily if the purpose sees fit.
