I have always been fascinated by large trucks, especially the Caterpillar-type earth-moving equipment. It was difficult for me to actually go to and attend a construction site with such machines moving around. So I went tidrectly to the Grenoble headquarters, and found that on top of various visual brochures,they in fact had small-scale models of their mest-known machines. So I bought one and could use it from all angles to provide a realistic touch to the dragon-truck...

This also was for me a great opportunity to improve my drawing of horses.
