HISTORY
"Capacity Day" was an annual corporate sales competition held in the 1950s where Sinclair service stations competed to pump their highest possible volume of gasoline. High-performing franchise dealers and distributors who met or exceeded top corporate sales targets were awarded premium recognition incentives—making this box a limited corporate piece rather than a mass-market giveaway.
