Under certain circumstances, we prefer to simply use the marque on its own instead of the full logotype. In general, these are communications where the Black Box brand has already been established. Alternatively, there will be situations in which we will want our brand to appear more recessive. In these instances, we want the graphics to be the main element and the icon to act as a subtle sign-off. The marque is reserved for usage by Black Box only.
Note that while the marque can exist without the logotype, the logotype should never exist without the marque.
