How to combine elements.

A combination is formed when multiple elements are taken from an even greater amount of elements, and are assembled or compiled.

If, for example, you're developing a logo that will be used in several areas, it is advisable to create a logo that can be easily varied for these different applications. However, it should always be possible to establish the relation to the original logo.

The variations of one logo must always be limited to one client - if the client requests them anyway. Common sense should tell you that you should never sell a variation of a client's logo to another client.
