Tempo Curacao 15th Anniversary Logo
This logo goes ultra simple with a large, block number fifteen in the brand's light gray color. Inside the circle of the number five they've placed their round, original logo in their usual red. Just to add another tiny bit of clarity they've placed the word "years" below the number inline with the red of the logo. It relies heavily on their market being able to recognize their mark, but it does a great job of building on that brand awareness in a simple, clean package.
