The Red Disc appeared on Coca-Cola advertisements as a red disc in the late 1940s.
The Red Disc was a bold circular Coca-Cola sign and graphic device that placed the white script wordmark against a strong red field. It helped make the brand instantly visible on storefront signs, delivery equipment, and outdoor advertising.
The design belongs to the period when Coca-Cola was consolidating red as a central brand color. The disc could be read from a distance and reproduced consistently across different materials, making it useful for retailers as well as for national advertising.
The Red Disc should not be confused with the later Dynamic Ribbon. The disc was a circular presentation of the brand, while the Dynamic Ribbon was the white wave introduced in the 1969 identity system.
