A symbol and a seal
The symbol identifies the initiative; the seal identifies those who endorse it. Here is what they mean, how to use them and the files to download.
The round seal, for 96 px and up.
The horizontal seal, for email signatures and small sizes.
The symbol, the icosahedron, identifies the initiative. Endorsement is shown by the seal. Why an icosahedron
The symbol: twenty faces
It is an icosahedron, a solid made of twenty triangles. Each face is one of the twenty behaviors by which good leadership is recognized. Hover over it, or tap, to see them.
The team explains its priorities in the same words as the person who leads it.
Twenty faces, ten in view. From any angle, you never see more than ten faces of an icosahedron. The same is true of anyone who leads: what you see depends on where you stand. The team sees some faces, the board sees others, and the leader sometimes misses their own. That is why the principles ask you to compare perspectives.
Each face, a behavior. The twenty faces are the signals of how good leadership is recognized, grouped under the seven principles. The principles state what you believe; the faces show what anyone can see from the outside.
Made for the unpredictable. Plato linked the icosahedron to water [26], the element that takes the shape of whatever it meets. Leading means moving among many variables that no one fully controls, and of the five regular solids, the icosahedron has the most faces.
No letters. It is a symbol anyone can read in any language, so it carries no initials. It is drawn as a stencil, in a single color, with an equal gap between faces. Its usage guidelines are further down this page.
Each face is a triangle: it rests on good governance and rises through management and leadership. The triangle principle
Usage guidelines
- It is for those who have endorsed the principles, for as long as their endorsement is current. It carries the year of endorsement and is renewed with it.
- Always use it exactly as supplied: do not change its colors, proportions or text. There are versions for light and dark backgrounds, with a solid or an outline symbol.
- Where the medium allows, link it to buenliderazgo.org.
- It signals a public commitment. It does not certify that the principles are met, and it must never be presented as a certification, accreditation or award.
- It may be withdrawn from anyone who uses it without having endorsed, or in a misleading way.
When your endorsement is confirmed, you also receive the seal with your number.

Each piece comes in four versions: positive and negative on a transparent background, on white and on black. The SVG looks the same in any program, because the text is converted to outlines; the PNG is high resolution.
