I have designed some sets of figures that can be used for shirt numbers. Starting point for all designs was that they should be drawn with a visible contrast between thick and thin strokes, expressing the dynamic qualities in sports games.
Another guiding thought is that each figures must have its individual character and that all figures together make up a cohesive team. As stated in the theory section/construction the 8 has to be drawn by one ongoing line. He is the perpetual motion machine, the driving force of the team. The 3 is like a statue in honour of the spinning ball with its nice curvatures. The 4 stands for the technical tour de force like the scissors movement and the kick with the back of the heel. And don't overlook the 0, the player that is almost invisible. He is always standing behind other figures and thus multiplies their worth by ten. So, each figure has to have its own characteristics, and in the mean time all figures together must breathe a cohesive team spirit.
The first design were the King's figures, which were used by Willem II. Although a contour was used, the legibility on the red-white-blue striped shirt still wasn't optimal. Therefore I designed King III, which is bolder.
Later on Prince was born and Champ.
