Due Tres Quattro by Manfred Klein is a free animal dingbat font built from solid, hand-drawn silhouettes. Its collection spans beetles, dragonflies, livestock, rabbits, and a lean canine figure, with lively contour lines and occasional ground strokes.
It can bring a rustic, storybook edge to farm-shop packaging and children's publishing. The same pictorial forms also suit wildlife event posters and nature-themed merchandise. Used as badges or repeating borders, the symbols become part of the illustration rather than ordinary lettering.
