NASCAR 75th Anniversary Logo
While other anniversaries use the diamond as the traditional shape, the 75th is absolutely one of them and NASCAR leaned into this with their design. A black oval representing the track their cars race around holds the name of the organization and recognition of the anniversary while a yellow, red, and blue diamond in the brand's traditional colors sits inside. A small ribbon then extends to either side of the diamond holding the years of operation.
